So I challenge people to give me a two-digit number times 11 and I can get the answer (even drunk) faster than they can type it to verify into their phone and they are then super impressed.
But the trick is actually really easy 27 * 11 = ... 2 + 7 = 9 so you stick a 9 in between the 2 and the 7 and the answer is 297.
45 * 11 = 495 (notice that 4 + 5 = 9)
The "hard" ones are when there is a carry. 48 * 11 = 512 (4 + 8 = 12 so there is a carry and the hundred's place is one more than 4)
If you do math tricks while drunk without explaining there is a trick, it blows people away. (I'm literally paid to outsmart 5th graders. This is my job. Squaring two-digit numbers that end in five is another of my go-to tricks that confuse people.)
