Hi, everyone.I am doing some problems where i have to in effect do two separate problems, then subtract the sum of the second problem from the answer of the first. But I am having trouble keeping the numbers straight. How can I save the numbers so that I can paste them back into the calculator--like 3-1 ... thgat's simple, but that's what I need to do. I read something about memory, but I deon't know or understand how to use it--the temporary memory, I mean.
Anyone got ideas? Jane
