Let’s take
Ok, so what you have to do is split up the numbers, giving you
And
Forget about the for the moment and do this:
Always add 1, adding 1 to the 4, so we get 4 + 1 = 5
Then multiply this answer, 5, by the original first number, 4
5 X 4 = 20
So what you have is 20 and
Everyone knows = 25 right? Well it does. This is what makes it easy.
Put the two answers together and that's the answer!
2025
This works for any number ending in but when the numbers get over 100 it tends to get a little trickier with the multiplication.
Give it a try with another number.
Try , it isn't difficult.

Split the numbers apart:
8 and
Again, forget about the
Add 1 to 8
8 + 1 = 9
Multiply 9 by the first number, which was 8
9 X 8 =72
Now, put all the numbers together, 72 and
= 25
So the answer is 7225
Try it out in a calculator once you have done it. http://www.memorymentor.com/
