With the development of smartphones that come pre-installed with calculators, mental math has become obsolete.
We all rely on the convenient app to assist us with our math needs, whether it's when we're calculating bills, adding up our monthly spending, or determining whether we can afford that expensive buy.
But it appears that a lot of us haven't been taking full advantage of this tool and haven't known about a number of tricks that can greatly simplify the process of working out your numbers.
It turns out that when we accidentally make a mistake with the numbers, we don't have to click 'C' to undo all of our hard work.
Most Apple users are unaware that there is, in fact, a far more effective approach to tidying up your mess.
You may simply remove specific numbers from the calculator app on your iPhone, saving you the trouble of having to start again while adding.
To delete an undesirable digit and resume where you left off, just swipe left or right across the screen.
Thus, you may bid adieu to having to redo every computation because of a single, insignificant mistake.
As The Jackson Five once stated, it's as simple as one, two, three.
There's a technique for it too, if you're trying to save time when doing your math.
You can duplicate the result of a calculation you just completed without even opening the calculator again if you finished it and moved on to another program.
To duplicate your latest figure, just press and hold the app. An icon will then display.
Although many of us mistakenly believe the iPhone calculator to be a basic tool, it actually has a ton of functions. For instance, the program can also be used as a scientific calculator.
In order to access the scientific buttons, you must first make sure that your phone's screen orientation is not locked. To do this, flip your phone lengthwise.
Turn it on its side to access the scientific calculator, which offers logarithmic and trigonometric functions, after making sure it's not locked.
The scientific calculator has also additional hidden features that can be accessed by pressing the "2nd" button.
Additionally, the scientific calculator has a pretty peculiar feature that lets users produce random numbers by pressing the 'Rand' button located in the bottom right corner. This feature could be helpful in a game, for example.
You can also quickly and without losing any of your calculations switch between the standard and scientific calculators.
You won't lose any progress because the software will maintain track of any calculations even if you switch to the other mode.
