Method #2- Subtracting Whole Numbers

Subtracting is a little trickier, but it can still be done in your head also. Try to subtract 455 from 1,000. That's alot to remember, isn't it?

Since you have probably learned the usual method of subtracting on paper- that is, writing down the 1,000 and then placing a minus sign at the left of the problem and then writing down the 455, drawing a line underneath, and beginning to subtract starting at the farthest number on the right side-you are probably thinking that there is noway you can put all of those numbers in your head and remember them! Well, there's good news- you don't have to! To subtract these numbers in your head, think of it like a cashier making change. Simply add instead of subtracting.

We do this by adding numbers onto the 455 until we reach 1,000. 455 plus 5 equals 460; 460 plus 40 equals 500; 500 plus 500 equal 1,000. Then we add the numbers 5+40+500 and come up with the sum of 545. Or, you can take the 455, add 500 to make 955, add 40 and then 5 to come up with 1,000. There are several ways you can add the lowest number, or the number that you wish to actually subtract from the highest number, to other numbers to come up with the 1,000.
