Maths Trick Blows People’s Minds On Twitter

Sky News:-  Figuring out percentages can be a nightmare – especially if you haven’t got a calculator to hand.

But now, a maths whizz has blown people’s minds on Twitter after sharing a simple way of working out complicated sums.

The “fascinating little hack” involves flipping the numbers around to make things easier.

For example, if you need to work out 18% of 50, swap them and go for the easier option of 50% of 18 instead. The answer for both is nine.

Another example is 4% of 25. Flip it round to work out 25% of 4 – and the answer to both is one.

The formula was tweeted by Ben Stephens from Brighton, and it has since attracted more than 11,600 likes and 4,000 retweets.

Others said they were “terribly impressed” and questioned “why was I never taught this in school.”
