Paul got a box of 457 erasers and 617 crayons for his birthday. At the end of the school year he only had 523 crayons left while not having lost a single eraser. How many more crayons than erasers did he have left?
If he had two fewer crayons than erasers, that would mean he had an equal number of each. Two fewer crayons than erasers would also mean he had two more erasers than crayons.
