Abacus/Manual/Quick use/Subtraction

< Abacus‎ | Manual‎ | Quick use

Subtraction, as you may already know, is the opposite of addition. Simply just take away the numbers that you have put on from your original number. Heres an example:

  • 5-2=3
111110 101-
111011 110=
110111 110

Practice these till you can figure it out. It may not be as speedy to make out but over time im sure you will have a good course in it.
