Math Lesson 1

Example 1

balloon balloon balloon balloon balloon balloon balloon balloon balloon balloon
1 2 3 4 5 6 7 8 9 10
Above we have 10 balloons

balloon balloon balloon
1 2 3
If I took away 3 balloons

balloon balloon balloon balloon balloon balloon balloon
1 2 3 4 5 6 7
We would have 7 baloons left

So 10 balloons -minus 3 balloons = 7 balloons or 10-3=7

1 2 3 4 5 6 7 8 9 10
Above we have 10 fish.

balloon balloon balloon balloon balloon
1 2 3 4 5
If we ate 5 fish for dinner.

balloon balloon balloon balloon balloon

Then we would have 5 fish left.

So 10 fish -minus 5 fish = 5 fish or 10-5=5
