With this trick, in just 5 minutes you will learn how to quickly multiply 20×20 in your head. You could easily multiply 2 numbers from 11 – 19, with no calculator.

(A) Example: 14 x 17

Steps:

- Remember the larger number of the two (17)
- Add 17 from the second digit 4 (taken from 14): 17 + 4 = 21
- Get the sum (21) and add a zero on the last (or multiply it by 10): 21 x 10 = 210
- Multiply the second/last digit of the 2 numbers 4 (from 14) x 7 (from 17) = 28
- Add 210 + 28 = 238

(A) Final Answer: 14 x 17 = 238

(B) Example: 18 x 13

Steps:

**18****+ 3**(from 13) =**21**- Add a 0 to 21 = 210
**8**(from 18)**x****3**(from 13) =**24**- 210 + 24 = 234

(B) Answer: 18 x 13 = 234

## A Simple Magic Math Trick for KIDS:

This is for kids that want to do a simple magic math trick to their friends, parents, guardians, cousins, etc… Ask them to think of a number from 1 to 100. You are going to guess what number they are thinking by letting them take this 3 easy steps:

- Step 1: Tell them to multiply their number by 2
- Step 2: Then tell them to multiply it by 5
- Step 3: Then let them say what is the total number they come up

Then, to guess their number. Just drop the 0 (the last digit is always 0) from the answer they gave you ðŸ™‚

Sample: Mom is thinking of the number 15

- 15 x 2 = 30
- 30 x 5 = 150
- Drop the 0 from 150 = 15

Learning math is fun. So kids, don’t be lazy to go to school and have fun learning. “Knowledge is Power”
