Category | Definition | Example |
|---|---|---|
Natural Numbers | Contain all counting numbers which start from 1. N = {1, 2, 3, 4,……} | All numbers such as 1, 2, 3, 4, 5, 6,…..… |
Whole Numbers | Collection of zero and natural number. W = {0, 1, 2, 3,…..} | All numbers including 0 such as 0, 1, 2, 3, 4, 5, 6,…..… |
Integers | The collective result of whole numbers and negative of all natural numbers. | Includes: -infinity (-∞),……..-4, -3, -2, -1, 0, 1, 2, 3, 4, ……+infinity (+∞) |
Rational Numbers | Numbers that can be written in the form of p/q, where q≠0. | Examples of rational numbers are ½, 5/4 and 12/6 etc. |
Irrational Numbers | The numbers which are not rational and cannot be written in the form of p/q. | Irrational numbers are non-terminating and non-repeating in nature like √2 |

If m and n are the numbers, then the general form will be m + n = n + m for addition and m.n = n.m for multiplication.
Commutative
If m, n and r are the numbers. The general form will be m + (n + r) = (m + n) + r for addition(mn) r = m (nr) for multiplication.
Associative
For three numbers m, n, and r, which are real in nature, the distributive property is represented as: m (n + r) = mn + mr and (m + n) r = mr + nr.
Distrubutive
There are additive and multiplicative identities.
For addition: m + 0 = m. (0 is the additive identity)
For multiplication: m × 1 = 1 × m = m. (1 is the multiplicative identity)

Always work left to right and pay attention!!!!
If you do not put the problem in the calculator EXACTLY as it is, the calculator will be wrong. It is better to solve one piece at a time.

Multiple Choice
Solve the equation.
x = 0.6
x = 2.3
x = 4
x = -1

Multiple Choice
What is the first step in solving this equation?
add 4 to both sides
distribute the 4
subtract 4 to both sides
subtract 12 to both sides
