What's your age and shoe size?

What's your age and shoe size?

A clever arithmetic trick that can calculate ones shoe size and age in just a few quick “no brainer” steps has gone viral on Twitter. 
 
Although the trick is not quite new, it has found its way back to the “Twitter-Sphere” last week creating a huge amount of engagement and enthusiasm from our fellow users. 
 
Although many found the trick amazing, there have been a few who did not find it exciting at all. 
 
So, why not give it a try and see what you think about it? 
 
All you need to do is follow the simple equation or Maths steps below:
- To begin, find a participant, and, ask them to write down their shoe size without showing it you, or “out of sight’ 
- Ask them to multiply the number above by five
- Then, ask the participant to add 50 
- And then multiply it by 20
- Ask the participant to add 1015
- And lastly, subtract the figure by the year in which they were born 
 
The figure you are left would should include their shoe size and age, in total comprising of just a three or four digit number. Example (524), Shoe size 5, and age 24. 
 
The trick works regardless of whether you use UK, European or American shoe measurements.
 
Be quick to try this out as soon as possible as the trick not work to well later in the year. Reason being, once you have had your birthday, the figures are out. 
Some people found the trick marvellous such as Peter Campbell (Actor) who referred to it as “witch craft”
 
Others were not so overwhelmed, such as 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?" 
 
Carol Vorderman, who is a former Counter maths guru is definitely a fan, “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.”
