Basic Subtraction Lesson 1: Number 1

Welcome to Basic Subtraction. In this unit, you will learn how to subtract numbers from one to twelve and also zero. FoxyMath wishes you success!

Here's an easy example:

3
-
1
=
2
 
      
-
  
=
    
 
   LawnGreen Box   Khaki Box   Turquoise Box  minus     LawnGreen Box  equals     Khaki Box   Turquoise Box

We start with three boxes, take away one box, and now have two boxes. We take away one box from our three boxes to get two boxes.


Here's another example:

5

In order to do basic subtraction, you must memorize some equations but fear not: FoxyMath will help you! When you are finished with this lesson, you will know the following equations:

  1 - 1 =   0
  2 - 1 =   1
  3 - 1 =   2
  4 - 1 =   3
  5 - 1 =   4
  6 - 1 =   5
  7 - 1 =   6
  8 - 1 =   7
  9 - 1 =   8
10 - 1 =   9
11 - 1 = 10
12 - 1 = 11


The following exercise will help you learn the above equations and what they mean. Please take your time: take whatever time you need to learn the material.
