  • waste of time...cool trick though, but i wouldn't want to be drawing sticks....how do you do 26 x 7? double x  single digits...which is what we usually do in real life?

  • im not so good at math so this is ingenius..thx bro its working for me!

  • it didnt work... the numbers for multiplication have to be equal. Like 4 numbers * 4 numbers, it didnt work with 3numbers*4numbers... Or am i wrong?

  • @Marvin250 sorry, but your wrong. I tried it for 26x143 and it worked. it works for any number, as long as you are adding the right numbers... you add those diagnol from eachother all the way across the chart. try setting it up on a diagnol and just adding them vertically

  • What? Wait... Whoa... How did you find this out? I even pulled out my calculator to solve these and the answers are correct... Wow... I'm pretty much speechless...
