Practice Repeated Operations in Math
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
Applying the same operation multiple times in succession, where the repetition is often compressed into a higher-level operation: repeated addition becomes multiplication (), and repeated multiplication becomes exponentiation ().
