THE ODIN PROJECT
// objective -- never use eval -- build your own functions to evaluate expressions
// expectations -- add sub mul div -- num, oper, num -- use variables for these threes' -- operate(oper, num1, num2) -- create numInput for operations -- operate() when = is pressed - update the display with result - store values is hard part -- watch for bugs - evaluate single pair at a time - round off your answers with long decimals - = before entering all numbers can cause problems - clear should wipe all the data - n / 0 should give error message
