Basic Subtraction Lesson 5: Number 5

Here's an easy example:

6

5
=
1
 
            
-
          
=
  
 
   Khaki Box   MediumBlue Box   Turquoise Box   DarkSeaGreen Box   MediumSpringGreen Box   SlateBlue Box  minus     Khaki Box   MediumBlue Box   Turquoise Box   DarkSeaGreen Box   MediumSpringGreen Box  equals     SlateBlue Box

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


Here's another example:

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:

  5 - 5 =   0
  6 - 5 =   1
  7 - 5 =   2
  8 - 5 =   3
  9 - 5 =   4
10 - 5 =   5
11 - 5 =   6
12 - 5 =   7
13 - 5 =   8
14 - 5 =   9
15 - 5 = 10
16 - 5 = 11
17 - 5 = 12


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.
