Negative Numbers and Integers
Integers include positive numbers, negative numbers, and zero, helping us represent values below zero, like temperatures or debts.
Core concept
Negative numbers are numbers less than zero, shown with a minus sign, like -5, representing values below a reference point.
How it works
Integers include all whole numbers and their negatives: ...-3, -2, -1, 0, 1, 2, 3...
Why it matters
We use negative numbers in real life, like representing temperatures below zero or money owed (debt).
Key detail
On a number line, negative numbers are to the left of zero, and the further left, the smaller the value.
