Canon LS-82Z Calculator This instant

One other reviewer said the change sign button is on the % sign. Well, it isn't actually. There is no change sign button. What the + - on the percent button means is you can add or subtract percent easily. For example, you can key in 100 + 6 % to add 6% to 100... It is a small calculator, but perfect for balancing a checkbook. Perfect size for what I was looking for. I do wish it had a change sign button, however. That would get it 5 stars then.Get more detail about Canon LS-82Z Calculator.
