Practice Negative Numbers in Math

Use these practice problems to test your method after reviewing the concept explanation and worked examples.

Quick Recap

Negative numbers are numbers less than zero, used to represent direction, deficit, or values below a reference point.

If zero is sea level, negative numbers are depths below the surface — temperature −5° is 5 degrees below freezing.
