To find out percentages on a calculator, you'll need to know a few basic things. Like, what's the original number, and what percentage are you trying to calculate? For example, let's say you want to calculate 15% of 200 - you'd need to punch in those numbers and then hit the percentage button, which is usually marked as "%" or "%".
Now, I know what you're thinking - "which button do I press first?" Relax, it's not rocket science! Most calculators will have a specific button for calculating percentages, so just look for that and you're golden. It's like having a superpower in your hands, and who doesn't love that feeling?
So, let's say you want to calculate a tip at a restaurant - you can use the calculator to figure out 15% of the total bill. Just type in the bill amount, hit the percentage button, and then multiply by the tip percentage - voila! You've got your answer, and you can impress your friends with your math skills.
