1.1: Number Sets
Every number that we work with in high school is classified as a Real Number ( ). Within the Real Number System there are a variety of number sets:
- Natural Numbers: They are our countable numbers. = {1, 2, 3, 4, ...}
- Whole Numbers: Countable numbers and zero.W = {0, 1, 2, 3, ...}
- Integers: All positive and negative whole numbers. = { ..., -3, -2, -1, 0, 1, 2, 3, ...}
- Rational Numbers: Decimal numbers which repeat or terminate. These can all be written as a fraction.
= {..., -3.33..., -1.5, - , 0, √.16, 5.9, .....}
**N, W, and I are all sets within the Rational Numbers.
- Irrational Numbers: A decimal number which does not terminate or repeat. It cannot be written as a fraction.
= {...., 1.67983456...., , √12, ...}

You will be using the Perfect Square/Perfect Cube chart in the classroom, but on the final exam you will need to make your own. Try to do the following in your head:
Perfect Squares Perfect Cubes
* think repeated multiplication
Sometimes you will need to use larger powers. The nice thing about exponents is the larger they get, the shorter your list needs to be. Try these:
Powers of Four Powers of Five

So, how do we convert entire radicals to mixed radical form?
1. Find the largest perfect square that the radicand is divisible by (without making a decimal answer.) Use the chart.
3. The number / factor left over is the new radicand that stays under the radical sign.
