Operators

Mathematical Operators

Computers can be used to carry out mathematical calculations.

The symbols we use in maths are similar to the symbols we use with computers to say what calculation we want it to do.

We know we can set and store data in variables using the set block.

We can output the values using the say block

We can do more with values than just say them.

We can get the program to do some maths using the Green Operators Blocks

For example we can add two numbers together…

Watch the video below to see how to add up values using mathematical operators in Scratch.
