A subtraction table is a systematic arrangement of numbers that are written in the topmost row and topmost column.
- This arrangement of numbers helps us to find the difference between any two numbers by observation, not by traditional calculation.
- The table consists of rows and columns, with each cell representing the difference between the numbers corresponding to the row and column headings.
- The top row and leftmost column usually display the numbers being subtracted (subtrahends), while the interior cells contain the resulting differences.

Solved Examples
Example 1: Subtract 4 from 10 to 15
Solution
Number | Subtraction | Answer |
|---|---|---|
10 | 10 - 4 | 6 |
11 | 11 - 4 | 7 |
12 | 12 - 4 | 8 |
13 | 13 - 4 | 9 |
14 | 14 - 4 | 10 |
15 | 15 - 4 | 11 |
Therefore, the subtraction table for 4 is:
6, 7, 8, 9, 10, 11
Example 2: Subtract 12 from 50 to 55
Solution:
Number | Subtraction | Answer |
|---|---|---|
50 | 50 - 12 | 38 |
51 | 51 -12 | 39 |
52 | 52 - 12 | 40 |
53 | 53 - 12 | 41 |
54 | 54 - 12 | 42 |
55 | 55 - 12 | 43 |
Therefore, the subtraction table for 12 is:
38, 39, 40, 41, 42, 43
