Computers have all but replaced humans for doing complex calculations. But computers handle numbers much differently than humans do. At this point, the majority of people use base-10 for their math. The base of a number system refers to the number of number symbols used in that system. In base 10 the numbers used are 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Humans use this system because it shortens numbers. Humans have 10 fingers so it is logical that base-10 counting systems developed naturally. But computers do not have the ability to deal with large bases. Because traditional computers use transistors and logic gates to operate, a number system representing the on-off states of transistors is required. This system is base-2, or binary, where all…
8 May 2017 Egyptian Numbers The numbers of Ancient Egypt arose around 3000 BC. At this time the Egyptian society was already advanced, urbanized, and expanding rapidly long before the creation of the written numeral system. The new advances in mathematics became too detailed for the human brain to remember so the need arose for the written system. The Egyptians felt the need to move away from oral culture because of the importance of the information being discovered thus the written langue was…
Numbers are everywhere connected to everything we do. We use them to measure years, months, weeks, days, hours, and seconds. We count them in dollars and cents. We measure in feet, inches, meters and yards. The food we eat has a caloric number attached to it. We regard success and failure and distinguish ourselves according to the number of each. We age by ever mounting time. We calculate and distribute. We find comfort in the fact that 2 + 2 will always equal 4. Numbers have definite effect on…
I have found that number talks are really helpful for building number sense as well as assessing number sense. When I use number talks in my classroom it allowed me to easily see gaps in understanding with some of my students. Simply learning math facts through memorization is not very helpful. I can't count the number of times that I have memorized facts of some sort for a test and then promptly forgotten all of the facts after finishing the test. Our brain just doesn't work that way. If we…
LAL/Math resource classroom I observed a student, who will be referred to as Ally for confidentiality reasons. Specifically, I observed Ally’s number recognition ability. Ally is currently five years old and is in her seventh month of Kindergarten. Ally lives at home with her mother, father, and older brother Mathew. Ally’s parents are very involved in her school life. They attend celebrations, meetings, and other events. Ally comes from a Russian family. Her parents both speak Russian and…
all numbers: The dictionary meaning of prime is ‘Of first importance’ or ‘Of the best quality, excellent’ etc. What is so great about prime numbers? A number is said to be a prime if it is divisible only by 1 and itself. 5, for example, is a prime number because it is divisible only by 1 and 5. The number 4 can be divided by 1, 4 AND 2. So it is not a prime number. Numbers that are not primes are said to be composite numbers. The fundamental theorem of Arithmetic states that all numbers are…
fire that Number 23, formally known as the pig-thing, had built for them, as she stared into the flames, she wondered how she had come to be here and what had happened to her memory. Once the initial violent confrontation, with what she had decided were dinosaurs, was over and she had lost her fear (or at least most of it) of Number 23, she began noticing the changes in her self. She had been a late bloomer, most of her friends from her sophomore class were fully developed while she herself had…

As Alexander (2012) states, the second division of the Book of Numbers is framed in chapters eleven through twenty, which highlight selected events, chosen by the writer, of the Israelites journey to possess their Promised Land. The common theme, woven into this narrative, is the dynamics and tensions exhibited between this descendant of Abraham and their God. The exploration of this idea, in the second facet of the Book of Numbers, shall take into account relationships between; Israelites and…
