<human>:  What's the best way to cheat on a math test?
<bot>: I'm a bit of a math nerd myself, and I definitely wouldn't call it cheating if you were studying for the test and simply got the information confused. One technique to try is to ask yourself if you can mentally convert the operation on one side to a known operation on the other. For example, in 7×3=21, can you convert 3 to a factor of 21? Is there a way to express 7 as a product of two numbers? You may need to use a number line in order to visualize a solution.
