Use Google to Do Math
Who needs a calculator anymore, right? You can just use the Calculator app on your iPhone, or better yet, let Google do the calculations for you.
Yes, Google has its own built-in calculator that can help you with any calculations. The best part is that you don’t have to know how to write the calculations; all you need to do is type in what you want Google to do.
For instance, you can just write “square root of 25,” and Google will show you the answer with its own calculator so you can keep working on calculations.
