Could someone please explain the difference between rational, real, natural, etc numbers?

Question

For my Algebra 2 test tomorrow I have to be able to look at a number and list all the characteristics about that number.

Reals-no clue

Rational- Understand

Irrational- Understand

Wholes- numbers like 4, 5, 9 etc not 2.34....am I right?

Integers- ?

Naturals- Numbers that you would start counting at (not 0) ex: 1,2,3,4,5,6.......

Answer 1

Real numbers are basically actual numbers that exists. That includes rational, irrational, whole, integers, and natural numbers.

Rational numbers are numbers able to be put as a fraction.

Irrational numbers cannot be put as a fraction (ex: 3.141592)

Whole numbers are: 0, 1, 2, 3, 4, 5....

Natural numbers are: 1, 2, 3, 4, 5... (basically 0 is not a natural number)

Integers are numbers that are both positive and negative

ex: -3, -2, -1, 0, 1, 2, 3, 4 (including 0)
