Answer to what?
Do you want to get the sum when the input is "+" and subtraction when given input "-"?

You sound like you want to go back to using a spreadsheet. MATLAB is not a spreadsheet.

See https://www.mathworks.com/matlabcentral/answers/143088-real-time-detect-keypress#answer_285124 for a list of key press processing available by using the third-party Psychtoolbox
Other than that, you have to have a figure up and use a KeyPressFcn callback; https://www.mathworks.com/help/matlab/ref/matlab.ui.figure-properties.html#buiwuyk-1-KeyPressFcn
