Practice Base-Ten System in Math
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
A number system using ten symbols (0-9) where each place represents a power of ten.
We group things by tens—probably because we have 10 fingers.
Example 1
easyExpress 5{,}304 as a sum of powers of 10.
Example 2
mediumWhy does multiplying any whole number by 10 append a zero? Explain using the base-ten structure.
Example 3
easyWhat is the value of 10^0, 10^1, 10^2, and 10^3?
Example 4
mediumA number N = 3 \times 10^4 + 7 \times 10^2 + 5 \times 10^0. What is N?
