The purpose of this chart is to help you learn your subtraction facts.  Your job is to MEMORIZE this chart!
As you can see, zero subtracted from any number does not change the number.
To use this chart, use the row for the larger number and the column for the smaller or same number that you are subtracting,
and find where this row and column intersect.
See the example below that demonstrates that 5 - 3 = 2.
