The two most critical things in Excel that are not obvious:
$
and
Solver
The $ is for coping and pasting cells where you don't want Excel to automatically change the formula. For example, suppose cell A1 had a value of 10 and cell A2 had a value of 5. Then suppose you typed '=A1' into cell B1. Obviously, B1 will now equal 10. If you copied that into cell B2, what is the value?
Logically, you'd think that if B1 = A1, and you copied B1 into B2, that B2 would equal A1. You'd be wrong. Excel automatically changes things when you copy and paste. B2 is equal to A2 (which has a value of 5), not the A1 (value of 10) that you'd expect. So, to keep the A1 in the formula, you must do this: '=A$1'. The dollar sign says do not change that number 1 automatically. If you want that A to stay constant, then you do this '$A1', or for both A and 1 to be constant do this '$A$1'.
The solver add-in can wait until you know a bit more, but it is the single most powerful and most useful part of Excel.
