Arithmetic operators (performing calculations)

To perform calculations, computer programmers use arithmetic operators.

Here are some examples of calculations using arithmetic operators and variables:

Add
SET total TO a+b
Adding the value of variable a to the value of variable called b. So if a contained 6 and b contained 2, the value 8 would be assigned to the total variable.
Subtract
SET total TO a-b
Subtracting the value of variable b from the value of variable called a. So if a contained 6 and b contained 2, the value 4 would be assigned to the total variable.
Multiply
SET total TO a*b
Multiplying the value of variable a with the value of variable b. So if a contained 6 and b contained 2, the value 12 would be assigned to the total variable.
Divide
SET total TO a/b
Dividing the value of variable a with the value of variable b. So if a contained 6 and b contained 2, the value 3 would be assigned to the total variable.
Exponent
SET total TO a^b
Raises the value of variable a to the value of variable b. So if a contained 6 and b contained 2, the value of 62 would be assigned to the total variable. In this case 62 is 36, so the value 36 is assigned to the total variable.
