# Solving Simple Sentences By Inspection

In this exercise, you will practice solving sentences ‘by inspection’. That is, you will look at the sentence, stop and think, and come up with a number that makes the sentence true.

Some sentences have exactly one solution. Some sentences have many solutions; you will provide only one. You should do this exercise without using a calculator.
