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.
Example 1
easyThe temperature was -8°\text{C} in the morning and rose by 15°\text{C} by noon. What was the noon temperature?
Example 2
mediumEvaluate (-3)^2 - (-2)^3.
Example 3
easyEvaluate (-4) \times (-7) \times (-1).
Example 4
easyA submarine is at -35 meters. It rises 12 meters and then sinks 7 meters. What is its final position?
