In computing, we work with lots of different forms of data. But the real fun comes when we can *do* something with this data.

In this lesson, we’ll look at how we can write short computer programs using *operators*.

Operators are different symbols that represent an *operation*, such as the plus sign (`+`

) as a symbol for addition. Operations enable us to *process* our data, to transform it into something else.

You may already be familiar with operators and operations from other contexts. This lesson looks at different ways we can use operators in programming, including:

- Making calculations using
*arithmetic*operators. - Comparing information using
*comparison*operators. - Creating logical expressions using
*logical*(aka Boolean) operators.

### Instructions

We can think of writing a program as similar to following a recipe.

In this lesson, we’ll look at how we can use operators to make a fruit salad.

To make the salad, we’ll use operators to:

- Calculate the fruit needed
- Compare the different fruits
- Determine if we have the right ingredients

Right now, we can only add or take away data points by manually including them or deleting them from our code, sort of like adding and subtracting.

When you’re ready, move to the next exercise.
