So with that in mind, let's go down a few lines below the if statement in the equalWasPressed method, and then we're going to create a conditional statement that checks if the current mode is equal to addition. So if currentMode is equal to, so two equal signs and then .addition and then some curly braces. If that's the case, we're going to add our two numbers together. So savedInt, that's the first number, +=, in other words, increment by the amount of, and then a space, and then currentInt, the current value that is in the calculator.
