Integers
Positive and negative whole numbers, zero, and the rules for combining them.
What this topic covers
- **Integers** are whole numbers including negatives: \(\ldots, -2, -1, 0, 1, 2, \ldots\)
- On a number line, values grow to the right and shrink to the left.
- Adding a negative is the same as subtracting: \(5 + (-3) = 5 - 3 = 2\).
- Subtracting a negative is the same as adding: \(4 - (-2) = 4 + 2 = 6\).
- Same signs multiply to a positive, different signs to a negative: \((-3)(-2) = 6\), \((-3)(2) = -6\).
