WATCH: The Internet's reaction to a 'new' iPhone function is amazing
Yes really!
A 19-year-old student from the USA has just revolutionised the way some people use the calculator on their phone and their reaction to it is amazing.
Jazz Johnson, a student at Baylor University in Texas, posted a short video on Twitter yesterday and it's already seen over 23,000 retweets and 27,000 hearts.
Why?
Because the video 'reveals' a function on the iPhone calculator that it seems a lot of people didn't know about, although the function has probably been there for a while.
The video shows how you can 'backspace' just by swiping. Don't believe us? Take a look...
It turns out that a lot of people didn't know about this function and this revelation is blowing their minds!
Here are some of the best reactions.
Some even wondered how much time they wasted having to restart their calculations.
