# Having Fun with Percents and the Ten-Key

Percentages are unique in that there are multiple ways to perform calculations with them. I'll share two methods. The quick way, and the other way.

## The other way

Let's start with the slow, long, you're-wasting-my-time method of adding a percentage of a number to same number.

We want to calculate **30,000 + 6% (of 30,000)**.

**[ 30,000 ] [ x ] [ .06 ] [ = ] [ + ] [ 30,000 ] [ + ] [ * or T ]**

Practical applications of this include sales tax and pay raises.

At 31,800, someone got a nice little raise.

## The quick way—or the way to a calculator's heart

**Press: [****C/CE**(or**C**) ] [**C/CE**(or**C**) ]**Press: [****30000**] [**x**] [**6**] [**%**] [**+**]

*See your total there on the screen now? I hope it shows***31,800**. If it doesn't, start over at #1 above.**Press: [****+**] [*****(or**T**) ]

*If you forgot that extra addition key, I'm sure you noticed that your lovely*If you didn't, congratulations! You can now add additional numbers to that or just clear it out and move on. Either way, you've accomplished something here and learned that there's a shortcut to lovely percents that takes all the hassle right out of 'em.**31,800**just flatlined it back to zero.

Aren't percentages grand?
