1x1=1 11x11=121 111x111=12321 1111x1111=1234321 11111x11111=123454321 There is another 11 trick. 11 *11 ok so you always put the 11 on top. Then the number on the bottom. The first digit goes on the left. then leave a space for the middle number. Then the second digit and put it in the right spot. Then add those together and put that numbe rinto the middle spot! ----- 121
