I often use these tricks to prove myself good in math’s although I am a very bad in mathematics. You can challenge your friends, that you are better than a normal calculator. How? just follow the process

Tell your friend to calculate 111111111 x 111111111 with the help of his calculator. ;)

Your friend will find the result too large to be calculated by a calculator. Now you can surprise him by giving the answer. The answer will be 12345678987654321

**How can you calculate**: When you multiply by the same number of 1's in both side then just count the 1's in 1 side. For example, in the multiplication 111111111x111111111 we have 9, 1's in each side. So type or write from 1 to 9 (123456789) . After typing 9 then start writing from the reverse (87654321). So in aggregate the answer will be 12345678987654321 .

IN THE SAME WAY ,

11 x 11 = 121

111 x 111 = 12321

1111 x 1111= 1234321

11111 x 11111 = 123454321

111111 x 111111= 12345654321

1111111 x 1111111= 1234567654321

11111111 x 11111111= 123456787654321

111111111 x 111111111= 12345678987654321

I hope you will understand the tricks from the example ;)

__Now the second tricks called "__

**without 8**"
Take a number of digits from 1 to 9 except the digit 8. So the number is 12345679

Now if you multiply the number by 9 the answer will be 111111111 .

Again if you multiply the number by 9x2 (18) the answer will be 222222222

again, if you multiply the number by 9x3 (27) the answer will be 333333333

**The whole example :**

12345679 x 9 = 111111111

12345679 x 18 = 222222222

12345679 x 27 = 333333333

12345679 x 36 = 444444444

12345679 x 45 = 555555555

12345679 x 54 = 666666666

12345679 x 63 = 777777777

12345679 x 72 = 888888888

12345679 x 81 = 999999999

I hope you will enjoy the trick, remember

**math is fun when you know how to play with it**;) Thank you for visiting PCTRICK.COM
