I only know of one way. It's called "addition with line break operator". The Keystroke is [Ctrl][Enter]. Essentially it breaks the equation at an "addition area". If you are subtracting, just add and make scalar value negative. In Version 14 help, look up "Addition Operators"

Thanks, but I'm trying to find the maximum value using the max(..) operation. I won't be able to use your suggestion since I'm only using commas and not +/- signs.
Put all the values into a vector, which can be vertical (or even two or more vectors if necessary) and pass max() vector arguments rather than scalar arguments.
