Order the following real numbers from least to greatest. Explain how you arrived at your conclusion?

Mathematical pi is spelled with two letters. It's a Greek letter π. You type that by holding the Alt key and typing 227 on the numeric keypad. Here are other characters:

Get a ruler in your hands. Measure things until you start to understand how a ruler works. Measure some stuff and figure out where the center is. Say you measure a book and it's 7/8" thick. You look at your ruler and see that every eighth is divided into two sixteenths, so obviously half of 7/8" is going to be 7/16". If you write that out you have 1/2 x 7/8 = 7/16. And you notice that 1/2 is divided into 2/4 and then into 4/8 and so on, so you can convert anything to anything by multiplying all the numbers on top and then all the numbers on bottom.

Other rulers are divided into 10 and 100 parts. But an inch is still an inch, so anything on one ruler can be translated to the other ruler. A half inch on one ruler is 5/10 or 50/100 on the other. An eighth inch is just 12.5 marks when you have 100 marks per inch. A metric ruler divides an inch into 25.4 parts, so a half inch would be 12.7 of those parts. Pretty simple, isn't it? Practice this a bit and people will think you went to wizard school.

Percent is simply a ruler with 100 marks. The only confusion is trying to keep track of what the marks represent, since that changes from time to time.

In most cases, not all, a number is defined to be the length of a line, positive lines to the right and negative lines to the left, and imaginary numbers at right angles to the real number line. That makes zero or any positive number larger than any negative number.

Knowing these things, you can get your answers by punching the given numbers into a calculator to convert them all to decimal notation. And you are correct: We use Shift-6 for powers.
