If you’re anything like most people, math is just not your strong suit. Seriously. Anything beyond basic elementary addition makes your head hurt and if the equation involves anything past “carrying the 2”, it’s a wrap. Math just flat out sucks and for most of the world, this is a universal truth. So, there was no surprise when self-proclaimed “Math Whizz” and Twitter user Ben Stephens tweeted out a simple trick for solving percentages, the internet went crazy.
Fascinating little life hack, for doing percentages:— Ben Stephens (@stephens_ben) March 3, 2019
x% of y = y% of x
So, for example, if you needed to work out 4% of 75 in your head, just flip it and and do 75% of 4, which is easier.
“18% of 50 feels hard to calculate.-Ben Stephens (Twitter)
But 50% of 18 is a doddle, right?”
So, pretty much, what you’re telling us, Mr.Stephens is that we’ve wasted most of our educational lives struggling, failing tests and risking zeros cheating on math quizzes with our TI-83’s discreetly tucked out of our teacher’s site whennnnnn we could have simply switched two numbers in an equation? Wow. Looks like the cyber world shares in our blown-away-dness too:
This sounds like something everyone should ideally have known in high school but I’m today years old when I realized I can’t think in even basic math— Sandhya Ramesh (@sandygrains) March 5, 2019

My calculator just blew up— Nigel Daniel (@Nobbydaniel8) March 11, 2019
Have a degree in Applied Mathematics and never knew that. 🤔— Kamal DJAIDAOUI 🇫🇷🇬🇧🇮🇩🇩🇿 (@DjaidaouiKamal) March 8, 2019
I just got a calculator to check this. Where was this fact 30 years ago?— Lee Robinson👾 (@bilbobarneybobs) March 5, 2019
Whoa…I teach Maths at primary level and had never realised this.— Magical Maths Notts (@MathsNotts) March 6, 2019

Cool. Thanks for helping get people enthusiastic about maths. You won’t believe this, but a lot of people find mathematicians rather smug and patronising. Crazy, right?— Ben Stephens (@stephens_ben) March 5, 2019
Maybe you could *swap* out the snark at people who struggle to do multiplication in their heads?— Ben Stephens (@stephens_ben) March 5, 2019
Why does this remind us of the smarty pants nerd that never said a word to anybody in class but was always the FIRST to remind the teacher about the homework from the night before that nobody did BUT HIM? Ugh.
It’s 87% of 43.— Pa (@paobriain) March 5, 2019
Case in point.
