**The Math Prezi Of Gabriel**

Math Prezi

In this prezi I will teach you about certain things about math, like vocabulary words, prime factorization, partial quotients, factors, multiples, and the divisibility rules.

Let's Start!

Vocabulary Words.

Let us start with some vocabulary words. Divisor is the number that divides the dividend. The dividend is the number that gets divided by the divisor. Divisor=1 / 2=Dividend. Net we have a prime number. A prime is a number that has only 2 factors, 1, and the number itself. A composite number however, has more than 2 factors, like 1x12=12, 2x6=12, and 3x4=12.

Prime factorization

Prime factorization is the process of finding the prime number that equal to a number. Exp:

24

/ \

12 x 2

/ \ \

6 x 2 x 2

/ \ \ \

3 x 2 x 2 x 2

The bold numbers are prime factorization of 24.

Partial Quotients

Partial quotients is a division method of long divison. Basically you do like 800/8, in the same way that you would put in long division, then you find the biggest number to take away from the dividend. In this this case, the largest number would be 100, so you do 8 x 100 and that equals 800, so you take the 800 and take away 800 and then, you get you answer, 100.

Factors

Factors are numbers that can make a number. Lets use 48 as an example. 1x48,2x24,3x16,4x12,6x8, Or:

1,2,3,4,6,8,12,16,24,48. Each number lines up with there counterpart on the other side.

Multiples

Multiples are numbers that are made my a number. Let's use 14. The first 6 multiples of 14 are, 14,28,42,56,70, and 82,

Divisibility Rules

Divisibility rules are how to find out how to divide by a specific number. The rules I'll be teaching are 2,3,4,5,6,9, and 10. 7 and 8 are for a later time. 2 can divide when a number is even, like 304. 3 can divide if the digits add up to a number divisible by 3 like 12. 4 is when the last 2 digits are divisible by 4 like 104. 5 is when the last digit is 0 or 5 like 425 or 10. 6 is when a number is divisible by both 2 and 3 like 12. 9 is when all the digits equal to a number that is divisible by 9 like 414. And finally, 10 is when the last digit of a number is 0, like 4370.
