The next time you need to “do the math,” do it in Excel with the basic math functions explained in Excel Video 231. Excel makes it easy to add, subtract, multiply and divide.

As you watch, notice that I always use cell references, not the actual numbers, whenever I can in my formulas. If my formula is =78.54 – 47.95, I’ll get the same answer if I use =B14-B13.
