A clever little trick

    Your Phone number will reveal your Age

    [1] Enter the last digit of your cell phone number, then =
    [2] Use this figure and multiply by 2, then =
    [3] Then add 5, then =
    [4] And then multiply by 50 then =
    [5] And then add the number 1763 then =
    [6] The last step; with this number, subtract your birth year then =
    Now you see a three-digit number.
    The first digit is the last digit of your phone number, the next digits is your actual age!

      Let the last digit of your cell phone number be "x" –
      [1] x (dat last digit)
      [2] 2x
      [3] (2x +5)
      [4] 50(2x + 5) or (100x + 250)
      [5] (100x + 2013)
      [6] (100x + your age) because of the 100 multiplier, the last digit of your phone number becomes the first digit of the 3-digit number formed, and the other 2 digits become your age.

      Ok, on the last step, it didn't give me a 3 digit number, it just gave me my age.

      Oddly enough, it worked like you said on my daughter, but it gave me my age straight out.

        I like how you keep changing your profile image/photo.

          Yeah, is that weird? Ppl do that a lot of FB. I get really bored with the same pic every day. I should probably be on some kind of meds.

        I noticed the trick doesn't work if your phone number ends in 0 or you're older than 99. So I'm guessing your phone number must in 0...or you've aged really well!

        If Martin had added a final step of dividing by 100, then the zero would show because a calculator displays decimals like this: 0.12.  (Just an example.)

          Well my phone doesn't end in 0 so.... sad
          It ends in 4. I used it on me, and it gave my correct age.
          I used the same phone # for my daughter and it gave the 3 digit # as he suggested.
          Im so proud of you for being so smart. Have I ever told you that? Well I am.

            For my own self-esteem I'll just take the comment at face value and not wonder if it was sarcastic or not, lol smile

              I only say sarcastic things if they make incredibly hilarious jokes... there's nothing very funny about "you're smart." Im always impressed with ppl who can do things I can't. (Which is a whole lot of ppl. lol) I'm used to the men in my life being very intelligent and good at complicated math... I've even known several women who excelled, my oldest daughter is one. But I am not gifted in this area, so it just makes me feel proud that you are. Just take the compliment and run, otherwise, you'll just feel awkward. I have that affect on ppl. wink

    LOL, I forgot to mention you need a calculator to do this on.

    Only needed a calculator for the last step. But it did work.

    This is a very old math trick - it's always fun, though - before cell phones, the formula used other numbers to trigger the process.
