1) The document discusses order of operations and prime/composite numbers. 2) For order of operations, parentheses, exponents, multiplication/division are done before addition/subtraction. 3) A prime number has exactly two factors, 1 and itself. A composite number has more than two factors. 4) Prime factorization is breaking down a composite number into its prime number factors and multiplying those factors.

- 1. By: Michael Bennett and Daniel Kim
- 2. Orders of Operations Parentheses-first Exponents-second Multiplication/division-third/fourth You do what is ever first in the problem Addition/Subtraction-fifth/sixth You do what is ever first in the promblem
- 3. An ex. of Order of Operations 3+5x10 2 -(9x9)/2= 3+5x10 2 -81/2= 3+5x100-81/2= 3+500-81/2= 3+500-40.5= 503-40.5=462.5
- 4. Prime and Composite Prime number-is a number that has two factors, 1 and itself. Ex. 3, 1x3; 23, 1x23 Composite number-is a number with three or more factors. Ex. 10, 1x10,2x5; 27, 1x27,3x9 0 and 1 are neither prime or composite.
- 5. Prime Factorization Prime factorization-is breaking down composite numbers into prime numbers and multiplying the prime numbers to get the original number. Ex.28, 28/2=14,14/2=7, 28=2x2x7 You multiply the divisor(s) and answer to get the original number Say it is a prime number, you would do nothing to it, it is already prime. Ex. 19=19, you can not divide it any more.
