Subtraction Input/Output Tables - within 20
We know that subtraction is the operation that decreases a number after the operation.
For example: Consider the table given below:
| In | Out |
| 14 | 11 |
| 19 | 16 |
| 13 | 10 |
| 15 | 12 |
Let's find the rule from the table given.
Notice that the given rule makes each number decrease.
Try subtracting 3 from each number.
14 – 3 = 11
19 – 3 = 16
13 – 3 = 10
15 – 3 = 12
Here, on subtracting 3 from the ‘Input’ numbers, we get the ‘output’ numbers.
So, the rule is subtract 3.
