#1 Fun with maths: Try out this equation to work out someone's shoe size and age

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.

#3 Maths fan: Former Countdown star Carol Vorderman said the trick was 'invaluable' because it made GCSE maths fun

The trick works regardless of whether you use UK, European or American shoe measurements.

However, the later in the year it is the less likely it is to work, because once you've had your birthday the figures are out so try it out now.

#4 Some people were thoroughly amazed by the trick, like Peter Campbell who said: "What is this new witchcraft?" and Kanja Kamonye, who simply said: "mind=blown!"

#5 But others were not so impressed, like Jon Williams, who said: "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?"

Former Countdown maths whizz Carol Vorderman is definitely a fan, telling the Daily Mail: "I love this great little game. It's simple algebra. It's incredibly valuable because it takes GCSE maths and turns it into something fun."
