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.
