Pretty cool math trick to use with your phone number, or any other seven digit number. It worked for me, so I'm assuming that it'll work for you. The next riddle will me out soon, I'm still deciding which riddle to use. Enjoy the video!

  • The rule is g+10f+100e+1000d+10000c+100000­b+1000000a=phone no. (((100a+10b+c)x80+1)x250+2(100­0d+100e+10f+g)-250)/2=1000000a­+100000b+10000c+1000d+100e+10f­+g.

  • what grade r u in...

  • You add 250, then later you subtract it. Couldn't you skip those two steps.

  • nah, the first 250 is multiplication, the second 250 is subtraction.
