Bug Operations not working

So i am using unity 2019.4.28f1 and i wrote some code to make a calculator and the operations were not working corectly

 

Can you be more specific?

 

From your code it looks like you are trying to do math with strings, which will not work. You'll instead need to parse the strings for numbers which you place in one of the numeric types of variables, such as "int" or "float". After that, then you can do math on those variables.

Here's one example:

You're not alone. The internet has over half a million videos to do this exact sort of thing. Who knew?
