This Maths Trick Is Our New Favourite Party Game
A weirdly clever maths trick can figure out a person’s year of birth and shoe size with just a few simple sums, but some online commentators aren’t feeling so impressed. Enter our parallel universe to find out why maths is suddenly cool on Twitter.
A maths trick that can work out someone’s shoe size and age in six easy-as-pie steps is making the rounds on Twitter, but is it any good?
According to online experts the trick has been around for years, but no one really cared (turns out maths equations don’t float many people’s boats – go figure!).
But since Twitter got its claws into the trick it has caused a furious debate on the social networking site, with some saying their minds have been blown, while others reckon it’s all a bit of a con.
Mind blown. Take your shoe size. Times by 5. Add 50. Times by 20. Add 1015. Subtract yr you were born. Answer = your shoe size and your age.— Lucy Tobin (@lucytobin) January 15, 2016
Here’s the trick so you can try it for yourself…
Find a willing participant and ask them to write down their shoe size, but not tell you
Then ask them to multiply that by five
And then multiply that number by 20
Then add 1,015
Finally subtract the YEAR of their birth
You should be left with a figure that includes their shoe size and age, together making up a three or four-digit.
Amazingly, the trick works regardless of whether you use a UK, European or American shoe size, but it does have a flaw. If you’ve already had your birthday in 2016 the figures are likely to be skewed…
Anyhoo, some people aren’t convinced noting that the trick literally ASKS for a persons shoe size and year of birth, so it’s hardly ‘guessing’ is it?
What's special about a maths trick that "guesses" your age and shoe size, when you have to reveal the year you were born and your shoe size?— Jon Williams (@pifflevalve) January 17, 2016
Has the world gone mad? The inputs to this are literally your age and shoe size https://t.co/cl8CDRAWsi— Richard (@gamray) January 16, 2016
I've found a really cool way of working out someone's shoe size and age. You ask them. And then you know.— Stig Abell (@StigAbell) January 18, 2016
