ahead. Jump from first number, counting

jumps equal to second number.

2 + 3

start from 2
1 2 3
jump jump jump

0 1 2 3 4 5 6 7 8 9 10

So 2 + 3 = 5

Add using number line.

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

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

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

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

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