The thing is that i am making a calculator. i wants when the user enter one or more digits the program push them in the array tab1 and as soon as he presses a non-numerical value, one of the operators, the array tab1 is pushed in the array tab before the operator. and at the end when he press the calculate() = the screen display the tab with tab.join('-'). But it fails.
