Subtraction Mojo (Overview)

Subtraction Mojo (Overview)

Subtraction is, as you know, the "opposite" of addition. The more you know about addition, the more you will understand subtraction. One of the coolest ways to do simple subtractions if you have to carry from the tens column, is to use addition! You will see this in the first lessons on this page.

If you are serious about achieving more meaningful insights into how your mind can deal with math, check out the Math Mojo series of booklets and downloads on the Ordering Math Mojo Materials page.For the time being, there is only one link on this page, but it is a good one. It is about left-to-right speed-subtraction. Other speed-math lessons will be up and linked to from this page soon.

If you have specific things you would like to learn, concerning subtraction, e-mail me your suggestions for future lessons.
