# LESSON

Mathematics can be quite tasking and boring. However, solving math on Scratch is simple and easy. Interestingly you don’t need a calculator and you can create a math quiz that could serve as a brain teaser to help build your math IQ.

**Arithmetic Operators**

You’ll find all the basic arithmetic operators on Scratch. The operators have special blocks that allow you to input numbers and solve simple equations. You’ll find multiplication (×}, division (÷), addition (+), and subtraction (-).

**Mathematical Functions **

Scratch also supports a large number of mathematical functions. Math functions that can be selected from the drop-down menu, include square root, trigonometric, logarithmic, and exponential functions.

**Random Numbers**

As you code, you’ll need to generate random numbers at some point, especially

if you create games and simulations. You’ll find random blocks serving this purpose.

*Let’s do math!*

Go to variable

Make a variable and name it as “Add”

Add a when “green flag clicked”

Then drag” set add to 0″

If you did this right, add will reflect on your stage with a 0 number

Go to operators drag the Addition lock and place on the 0

Input two random numbers

Now click the green flag and observe what happens on your stage.

**Task**

- Code for different numbers using different arithmetic operators.
- Code a quiz project. You can use the picture below as a guide.
