This is a simple calculator. I did it to get used to calculators, and have some practice with numbers. To add, Change the addens to the Number you want then click add. There is a answer in the middle. To multiply, change the Multiplicands, then click multiply. The answer is in the middle. To subrtact, change the minuend and Subtrahend, then click subtract. If you want to get a positive number in subtracting, you have to make the minuend greater than the Subtrahend.
