Lesson 13: Zero; Terms; Review

Zero

Zero is very easy to understand. Zero plus any number is the number.

0
+
1
=

+
  
=
  
 
 No Box   plus     Aqua Box  equals     Aqua Box

We start with zero, which is nothing, add one box, and now have one box.

Here is the addition chart for zero:

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

Similarly, any number added to zero is zero.

2

0
=

   Aqua Box   PowderBlue Box  plus   No Box   equals     Aqua Box   PowderBlue Box

We start with two boxes, add zero, which is nothing, and now have two boxes.

Given what you just learned, you now know the following equations:

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