Assigning values

### 4.5.2 Assigning values

You can assign a value to a variable with the := operator. For example, to give the variable a the value of 4, you can enter

> a := 4

Alternatively, you can use the => operator; when you use this operator, the value comes before the variable;

> 4 => a

The function sto or Store can also be used; again, the value comes before the variable

> sto(4,a)

After any one of these commands, any time you use the variable a in an expression, it will be replaced by 4.
