Module 1 Review

The few slides will be a review of everything we have learned so far in math class. Some slides will have a video. Watch it if you need help.

Remember: The number of 0's in our base 10 tells us how many times our digits are moving. If we are dividing our digits shift to the right, if we are multiplying our digits shift to the left.
