Abundant number

How are elements useful for a particular use? An element is made from one type of atom and this article is about the element Scandium. Scandium was discovered in the year 1879 by Scientist Lars Fredrik Nilson in the university of Uppsala. The origin of the name comes from the word Scandia, which is the latin name for Scandinavia. This element belongs to group 3 which consists of transition metals and Scandium shares this group with the element Yttrium. There are 4 groups in the periodic table…

Specifically, how old is counting? When was representing quantities thought of? Where did it start? Counting originated based on the needs of societies. For example, a primitive society did not need more than a few numbers to manage their life, while a more advanced society needed more than a few numbers to…

to discovering decimals. Although decimals are introduced in fourth grade they are continuously presented in math thereafter. One common misconception held about decimals is the idea that the more digits that are presented in a number, the greater the value of the number. An example of this is students believing that 3 is less than 0.7648 when this is definitely not the case. This misconception is related to Mariam Small’s third big idea where it is stated that by something about mathematical…

Part B Diagnostic Assessment During the diagnostic assessment which focused on grade three student, Boris’s comprehension of number placement and value, Boris did well in most areas, with minimal exceptions. Boris took a great deal of time, when requested to partition the double digit the number. Though they progressed to partitioning the larger numbers in a standard and acceptable non-standard manner, they answered the two digit partitioning question with various multiplication equations.…

possible 334 points. The teacher will divide the number of points earned, 299, by the total possible points, 334, with the answer of 0.895. The teacher then multiplied this answer by 100 creating the number 89.5. This number is able to be rounded to the nearest ten percent, 90%. The student achieved the qualification for a grade of A. The student would not be given the grade of A if the teacher truncates the whole number. Truncating the number to the nearest whole, would leave the student…

Ten fingers. What can we count on ten fingers? Most of you could count how many siblings you have, how many days until winter break, or how much money you have in your backpack. For me, I can count how many schools I've been to so far in my life, 8. It may not seem like a lot but consider they are towns, cities, and even countries apart.People say it's easier for me since I was "little" and I won't remember the friends I've made or worry about customs I had to change from moving to a different…

the black sheep,” singeling out Germanium as the “black sheep” although the pair of elements are “near twins.” Germanium and Silicon are both metalloids used in the technology and machine industries, however Silicon proved to be cheaper and more abundant, so Germanium has decreased drastically in it’s importance. To ensure further understanding of the scientific material, Kean uses personification. The author turns each lesson about an element into a full story with an introduction, climax,…

The number following the decimal point indicates whether the alloy is a casting (.0) or ingot (.1 or .2). A capital letter prefix indicates a modification to a specific alloy. Example: Alloy - A356.1 the capital A (Axxx.x) indicates a modification of alloy 356.1 the number 3 (A3xx.x) indicates Silicon plus copper and/or magnesium series. The 56 (Ax56.1) identifies the alloy within the 3xx…

the list goes on. I had a notebook in the third grade in which I would write numbers from one and beyond. Unfortunately that list was never finished; the fact that one could begin to write numbers from the day they were born to the day they would die and would not even be close to infinity is both scary and fascinating to me. This blew my eight year old mind. It sparked this passion in me to expand my knowledge of numbers, how they work and why they worked. Now I’m engaged in Calculus trying to…

of 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…
