Lesson 13: Zero; Terms; Review

Zero

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

No Box
plus
MediumSlateBlue Box
equals
MediumSlateBlue 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.

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
