How to Add or Subtract 10

If we choose a number on the number grid and move one place down, we are adding 10.

For example:

adding 10 to 10 on the number grid

If we begin with 10 and move one place down the number grid, we have added 10.

10 + 10 = 20.

adding 10 to 32 on the number grid

If we begin with 32 and move one place down the number grid, we have added 10.

32 + 10 = 42.

If we choose a number on the number grid and move one place up, we are subtracting 10.

For example:

subtracting 10 from 50 on the number grid

If we begin with 50 and move one place up the number grid, we have subtracted 10.

50 – 10 = 40.

subtracting 10 from 94 on the number grid

If we begin with 94 and move one place up the number grid, we have subtracted 10.

94 – 10 = 84.
