## Yes !! I do not need a calculator :)

I came across a trick to multiply numbers with 11 and come up with your answer before the calculator .

For example : 32 * 11 [For numbers which add up to less than equal to 9]

Just add the two digits : 3+2=5 and place it in between the original number 32 and tada 352 is your answer ðŸ˜€

99*11[Numbers which add up to a number greater than 9]

Add: 9+9=18

You again need to put this 18 in the middle of the original number but You have to add the 10s place number(obtained after addition) to the 1st digit of the original number .

(9+1)89 i.e 1089 is your answer

77*11

Answer : 847

Explanation : 7+7 = 14

Putting it in the middle : 7147

But you have to add 1 to 7 for the answer : (7+1)47 = 847

Start with this 2 digit number multiplication with 11 and display the MATHEMAGICIAN in you to your friends ! Enjoy ðŸ˜€
