any ideas of how you could make a calculator on scratch that can answer any math equation?

You could make buttons for 0,1,2,3,4,5,6,7,8,9 and +,-,x,/ and =

First, when the user clicks numbers, use the join operator to join them into one long number (Number1).
Then the user will click +,-,* or /. Store this operator in a variable eg. set Operator to +
Thirdly, get the second number (Number2) by again using the join operator as they enter numbers.
Finally the user will click =. Then you can combine Number1 and Number2 using the Operator and display the answer.


You will need more code if you want to add more features (eg. a clear button) or multiple calculations with intermediate results.

You can type Calculator in the Scratch Search Bar to see example projects.
