What is the distance between two integers on a number line?

Back

The distance between two integers is the absolute value of the difference between them. For example, the distance from -7 to 5 is | -7 - 5 | = 12.

What is the rule for adding integers with different signs?

Back

When adding integers with different signs, subtract the smaller absolute value from the larger absolute value and take the sign of the integer with the larger absolute value. For example, -7 + 2 = -5.
