# How to Solve a Math Problem

## How to Solve a Math Problem

Shouldn't we have started out with this? Oh, it's no big deal. You already know how to do all this business. It's just a little review of the general process, so this should all feel like old hat to you.

There are three steps to solving a math problem.

1. Figure out what the problem is asking.
2. Solve the problem.

Simple enough.

### Sample Problem

Doug went to the grocery store. He bought a bunch of bananas for \$1.37 and a jar of peanut butter for \$2.99. There was no tax (because he lives in the state of Simplified Math Problems—it's near North Dakota), and he paid with a ten-dollar bill. How much change will he get?

Let's work through the steps.

1. Figure out what the problem is asking.

We want to know how much change Doug will get. In other words, if he starts with \$10, spends \$1.37, and then spends \$2.99, how much will he have left? He wants to know so that he's clear about how much he'll have to blow on scratchers.

2. Solve the problem.

There are two ways to write this word problem as an arithmetic problem. We can write:

\$10 – (\$1.37 + \$2.99)

or:

\$10 – \$1.37 – \$2.99

Either way, Doug gets \$5.64 in change. That'll get him five \$1 scratchers, and he'll still have a bit left for laundry money. You go, Doug.
