Break It Down: Identify Key Information

The first step to solving a word problem is to identify the key information. Read the problem slowly and carefully, making note of any numbers or important details. In the example problem, “There are 5 apples, and 2 are eaten. How many apples are left?”, the key information is that there are 5 apples and 2 have been eaten.

Once you've identified the key information, think about what the problem is asking you to do. In this case, the problem is asking you to find out how many apples are left. Keep this goal in mind as you work through the problem.
