A maths trick that can work out someone’s shoe size and age in six simple steps has been dividing Twitter.
The trick has been around for years, but it cropped up again on the social media platform last week, causing a bit of a a rift among some people.
Some stated the trick had “blown” their minds, while others weren’t that impressed by it at all.
But what do you think?
Here is the trick to try 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
- Add 50
- 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 number.
