# Summary of the Math: Subtract Integers

**Read and Discuss**

The value of *a* − *b* is:

Positive if

*a*>*b*(if*a*is to the right of*b*on the number line).Negative if

*a*<*b*(if*a*is to the left of*b*on the number line).

Any subtraction problem can be rewritten as an addition problem by adding the opposite: *a* – *b* = *a* + (–*b*)
