Integers and Rational Numbers
Integers consist of the whole numbers and their opposites. On the number line, the positive integers are to the right of `0` and the negative integers are to the left of `0`. Zero is neither positive or negative.
A mathematical sentence that contains an inequality symbol is called an inequality.
The symbol `>` means greater than.
The symbol `<` means less than.
On the number line, numbers increase as we move from left to right.
The absolute value of a number is its distance from `0` on the number line. We use the symbol `|n|` to represent “the absolute value of n”.
