There are variables that set what the input numbers are, tells if the first input number has been chosen, sets what the selected operation is, and also strings that display the answers in the top box.
How does “parseInt()” help with the code?
It takes whatever numbers you have chosen and converts them into a string
What events are already specified? What needs to be added?
The event that was already specified was inputting and outputting numbers for addition of inputs 1 and 2. I added the other numbers and other operations.
