Do The Problem By Hand

We can't instruct the computer to do something unles we know how to do it first. So let's begin by doing a temperature conversion by hand.

Here's what I wrote down as I converted 40 degrees Fahrenheit to its Celsius equivalent.

Here's what I did step by step:

1. I began by writing down the amount to be converted, 40.

2. Next I subtracted 32 from it.

3. Then I multiplied the difference by 5/9.

4. The result was 4, meaning that 40 degrees Fahrenheit is equivalent to 4 degrees Celsius.

The next step is to look at what we did by hand and identify the corresponding computer commands.
