Part I-Classifying What is a number? How do you classify it?
Natural Numbers Natural numbers are the counting numbers: 1, 2, 3, …
Whole Numbers are the natural numbers and zero: 0, 1, 2, 3, … WH0le
Integers are whole numbers and their opposites: –3, –2, –1, 0, 1, 2, 3, …
Rational Numbers Are all integers, fractions,terminating decimals, square roots of perfect squares: -3, ½, 5, 8.74,
Irrational Numbers Can’t be expressed as a fraction or whole number. They include: • Square roots of non-perfect squares • Π, e, • Non-terminating decimals
After the game show…Keeping it straight! Real numbers Natural Numbers Integers Irrational Whole Numbers Rational Numbers
1. Commutative Property • Commutative Property of Addition--changingthe order in which you add does not change the sum. So, More Examples:
Commutative Property • Commutative Property of Multiplication--changing the order in which you multiply numbers doesn’t change the product. So, More Examples:
2. Associative Property • Associative Property of Addition--changingthe way the numbers are grouped does not change the sum. Add parenthesis to show Associative Property So,
Associative Property • Associative Property of Multiplication--changingthe way the numbers are grouped does not change the product. Add parenthesis to show Associative Property
3. Identity Property • Identity Property of Addition--if you add zero to a number, you get the same number! 0 is called the identity of addition!!
Identity Property • Identity Property of Multiplication--if you multiply a number by 1, you get the same number! 1 is called the identity of multiplication!!
4. Inverse Property • Inverse Property of Multiplication--anumber multiplied by its reciprocal equals 1.
Inverse Property • Additive Inverse Property--a number plus its opposite equals 0.
5. Distributive Property • A number outside parenthesis gets multiplied by every number inside parenthesis.
