# FIRST STEPS: MATHEMATICS
## Introduction @unplugged
Calliope mini offers you the possibility to use different mathematical operations. You can calculate numbers, create random numbers and save your results in variables.
## Step 1 @fullscreen
### Calculation of numbers
The Calliope mini is able to perform the 4 basic arithmetic operations addition, subtraction, multiplication and division out of the box:
You can find the required block in the menu Math. From the block's drop-down list you can choose between the four basic arithmetic operations and the exponentiation. To see the result of your calculation, you have to put the block inside a „show number" block from the Basic section. The Calliope mini displays the result of your calculation on the LED grid.
## Step 2 @fullscreen
### Random numbers
You can have Calliope mini create a random number: You can find the corresponding block in the menu Math ("pick random 0 to 10"). By changing the two numbers within the block, you determine how small or how large the random number is allowed to become.
