To multiply two large two-digit numbers, we subtract them from 100 to make the mathematical operation easier.
For example:
Let’s take 85 × 95
Subtract both the numbers from 100 100 – 85 = 15 100 – 95 = 5
Now, add the answers: 15 + 5 = 20
Subtracting this number from 100 will give us the first part of the final answer: 100 – 20 = 80
So, ‘80’ is the f
