...Binary Numbers Overview Binary is a number system used by digital devices like computers, cd players, etc. Binary is Base 2, unlike our counting system decimal which is Base 10 (denary). In other words, Binary has only 2 different numerals (0 and 1) to denote a value, unlikeDecimal which has 10 numerals (0,1,2,3,4,5,6,7,8 and 9). Here is an example of a binary number: 10011100 As you can see it is simply a bunch of zeroes and ones, there are 8 numerals in all which make this an 8 bit binary number. Bit is short for Binary Digit, and each numeral is classed as a bit. The bit on the far right, in this case a 0, is known as the Least significant bit (LSB). The bit on the far left, in this case a 1, is known as the Most significant bit (MSB) notations used in digital systems: 4 bits = Nibble 8 bits = Byte 16 bits = Word 32 bits = Double word 64 bits = Quad Word (or paragraph) When writing binary numbers you will need to signify that the number is binary (base 2), for example, let's take the value 101. As it is written, it would be hard to work out whether it is a binary or decimal (denary) value. To get around this problem it is common to denote the base to which the number belongs, by writing the base value with the number, for example: 1012 is a binary number and 10110 is a decimal (denary) value. Once we know the base then it is easy to work out the value, for example: 1012 = 1*22 + 0*21 + 1*20 = 5 (five) 10110 = 1*102 + 0*101 +...

...The Importance of Number Sense in the Elementary Classroom Robyn Thomas EDU Instructor: Dr. Silvernail November 2, 2011 Abstract In today’s elementary classrooms, students are expected to think and speak on high levels of intelligence. Teachers are encouraged to set high expectations, to question and probe and to ask students to explain what they are thinking. This paper will focus on the importance of understanding numbers or possessing number sense at the elementary level. The idea that students should already have some number sense is controversial. Struggling students in today’s classroom in the area of math seem to lack a major concept, which is a basic math skill or understanding numbers. What is number sense? Number sense refers to a person's general understanding of number and operations along with the ability to use this understanding in flexible ways to make mathematical judgments and to develop useful strategies for solving complex problems. Number sense develops gradually, and varies as a result of exploring numbers, visualizing them in a variety of contexts, and relating them in ways that are not limited by traditional algorithms. Most children acquire this conceptual structure informally through interactions with parents and siblings before they enter kindergarten (Marshall 2010) . Other children who have not acquired it require formal instruction to do so. For example, one child may enter school knowing that...

In mathematics, a real number is a value that represents a quantity along a continuous line. The real numbers include all the rational numbers, such as the integer – 5 and the fraction 4/3, and all the irrational numbers such as positive square root of 2,√2. Real numbers can be thought of as points on an infinitely long number line. In basic mathematics, a number line is a picture of a straight line on which every point is assumed to correspond to a real number and every real number to a point. Often the integers are shown as specially-marked points evenly spaced on the line. Although this image only shows the integers from −9 to 9, the line includes all real numbers, continuing forever in each direction, as shown by the arrows and also numbers not marked that are between the integers. It is often used as an aid in teaching simple addition and subtraction, especially involving negative numbers. On the number line, numbers located...

...complex number. Since a complex number z = x + iy is comprised of two real numbers it is natural to consider a plane in which to place a complex number. We shall see that there is a close connection between complex numbers and two-dimensional vectors. In the second part of this Block we introduce an alternative form, called the polar form, for representing complex numbers. We shall see that the polar form is particularly advantageous when multiplying and dividing complex numbers. 9 6 x know what a complex number is Prerequisites Before starting this Block you should . . . 8 y understand how to use trigonometric functions cos θ, sin θ and tan θ z understand what a polynomial function is { possess a knowledge of vectors 7 Learning Outcomes Learning Style After completing this Block you should be able To achieve what is expected of you . . . to . . . represent complex numbers on an Argand diagram obtain the polar form of a complex number multiply and divide complex numbers in polar form allocate sufficient study time briefly revise the prerequisite material attempt every guided exercise and most of the other exercises 1.

...Fibonacci Numbers In the 13th century a man named Leonardo of Pisa or Fibonacci founded Fibonacci Numbers. Fibonacci Numbers are “a series of numbers in which each number is the sum of the two preceding numbers” (Burger 57). His book “Liber Abaci” written in 1202 introduced this sequence to Western European mathematics, although they had been described earlier in Indian mathematics. He proved that through spiral counts there is a sequence of numbers with a definite pattern. The simplest series is 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144…and so on. When looking at this series the pattern proves that adding the previous number to the next will give you the following number in the series. For example, (1+1=2), (2+3=5), and etc. In order to ensure accuracy when using Fibonacci Numbers a formula was created. The formula or rule that follows the Fibonacci sequence is Fn = Fn-1 + Fn-2. By plugging in any numbers in a problem to this equation a student can find the right answer. This gives students the ability to calculate any Fibonacci Number. In modern times society uses these numbers to calculate numerous things. For instance, like the sizes of our arms relative to our torso and even the structure of hurricanes. On another note, Fibonacci Numbers can also be found in patterns in nature. It is truly astonishing to think about how relations in Fibonacci Numbers may possibly be represented in our lives.

...Number 40 The feeling of forgetting a phone, a name, and an address is simply frustrating and can mess with your head. It can make you quite uneasy and ruin the rest of the day. Some part of you is not really there, when you forget you’re most valuable belongings. The feeling of forgetting and delirious is exactly what we see in the short “Number 40” by Sarah Butler, from the anthology The Picador Book of 40, 2012. In the short story Number 40 we meet the anxious and unbalanced Melissa. Melissa is feeling anxious because she forgets a lot of things, and this time it is her phone. The short story is told through a third person limited narrator, where the narrator follows the forgetful Melissa throughout the story, and the reader is only able to read only her thoughts and feelings (s. 1, ll. 1-2) Melissa is living with her fiancé Simon: “Now they were living together”. “The ring Simon has given her two weeks ago” – “Three neat diamonds caught in three gold claws”. Simon has proposed to her, just two weeks ago. Melissa felt sick at the time, Simon proposed to her (s.3, ll. 84-85) she either felt vile because of the food or maybe she had a bad hunch towards the relationship. Moreover the relationship did not always seem to go as smooth (s.1, ll. 1-7) She feels like he is ignoring her, like she is not even there. The narrator uses flash back (s. 1, ll. 14-27) where Melissa and Simon was on vacation, where everything seemed wonderful and happy. But as soon as they came home...

...Random numbers in C++ and The Pythagorean Theorem Name Course Date Random numbers in C++ and The Pythagorean Theorem Introduction Computer programs in light of the technological advances that have been made, arguably make up for the most important concepts in such developments. A set of instructions designed to assist a computer to prefer a given task is referred to as a computer program. There are numerous languages used to create/design computer for instance Java Script, Java, C++, SQL and Sage (Laine, 2013). Computer programming is defined as a process of developing a working set of computer instructions meant to aid the computer in the performance of a given task. Computer programming starts with the formulation of a valid computer problem. This process is then followed by the development of an executable computer program, for instance Firefox Web Brower (Laine 2013). It is worth noting that there are other programs in the same realm. Computer programming is a diverse field that is of utmost importance in the modern world, especially with the continuous expansion of the internet. Perhaps the relevance of this can be underlined by the fact that computer programming has carved out as a course on itself. Computer programming is offered under several courses studied in colleges and universities (Laine, 2013). Computer programming is not only for computer students but for all who use computers on a day to day basis. This is by extension everyone since the...

...OK…So your tired of your current service provider. You’re tired of their sloppy customer service. Tired of having to speak to their discourteous customer representatives. Tired of receiving calls from unknown numbers in the middle of an important meeting only to hear “Kabhi Kabhi Aditi … ” being played and a mechanical female voice saying “Press 1 to set it as your callertune”. So…What would u want to do?? Change your service provider of course! Ah…but wait..you’re attached to your number! All of us are! Why change the number and put up with the trouble of having to remember a completely new one?? The solution to this seemingly never ending problem arrives in India, early next year in the form of Mobile Number Portability. Wondering what this is all about? Simple..you can switch between service providers without having to change your number and you can do this irrespective of the technology that you use. In other words, if you have a CDMA mobile and want to switch to GSM network, you can go ahead and do it with glee Of course, everything comes with a cost. But luckily in this case, the cost isn’t much high!! According to TRAI (Telecom Regulatory Authority of India), subscribers should not be charged more than Rs.19/- for changing their service provider. Mobile services will be disrupted for a few hours when the transfer is in process but this is again a minor hiccup. This service will initially be available only in metros and selected cities by early 2010. And thus...

...If an entire world can be expressed in ones and zero, then why not our living world? In seeing a random sequence of numbers such as 413270, it brings a slew of thoughts to mind. 314 are the first three digits of pi. 4, 3, 2, 1 speaks to me of the applied math and cause of history. 2.71 is my favorite number though an outdated concept for a mature individual. A random sequence of numbers can provide many memories. One of the saddest things lost in childhood is the interest in a favorite number. Nobody over the age of 10 asks another what their favorite number is. Perhaps as we mature we become less attached to certain digit sequences and closer to the meanings of such digits. A favorite number may end up being any numeral that represents a large sum of money. Favorite colors, shapes, and numbers lose importance as we grow and become more aware of our own wants and needs. My favorite number when I was 12 years old was the number 7. I had no particular love of 6 or 8 or any even number for that matter. My birth month, July, is the seventh month and 7 seemed to me to be a significant piece of my personality. It may seem absurd that a number may be of note for someone, but to a 12 year old girl or to a regular lottery ticket purchaser a number is the difference between happiness and misery. As I aged, my favorite number...
