Chapter.5 Integers
Add and Subtract integers
Integer Addition
Chip Model for addition-Black chips are used to represent positive integers and negative integers are red.
Charged-Field Model- Similar to chips but used the positive (+) and negative (-) charges.
Number Line Model- Always start at zero and move line to first number, then go to second number.
Pattern Model- Addition of integers can also be motived by using patterns of addition of whole numbers.
Absolute Value-The distance between the point corresponding to an integer and 0 is the absolute value of the integer.
Uniqueness of the Additive Inverse
For every integer a, there exists a unique integer -a, the additive inverse of a.

Properties of Integer Multiplication
Integer Division
The quotient of two negative integers, is a positive integer and the quotient of a positive and negative integer, is negative.
Order of Operations on Integers
The order of operations: parenthesis, exponents, multiply/divide left to right/ add/subtract left to right.
Order of Integers
Divisibility
If b l a, then b is a factor, or divisor, of a, and a is multiple of b.
Divisibility rules
Prime and Composite Numbers
Prime Numbers
Numbers in which there are only two factors or positive divisors. (ex) 2, 3, 5, 7
Composite Numbers
Numbers in which there are more than two factors or positive divisors. (ex) 4, 8, 12, 16
Prime Factorization
Factorization- Composite numbers can be expressed as product of two or more whole numbers greater than 1.
Prime factorization- factorization containing only prime numbers.
