# Math Notes

How I feel about math homework

Rational Numbers

- have an end or they repeat

- can be fractions and negative

- can be placed on a number line

Irrational Numbers

- numbers that have no end

- numbers that can not be placed on a number line

- examples would include pi and many square roots

Whole Numbers - are not negative and do not carry fractions

Integers - Are negative and positive numbers that do not carry fractions

Absolute Value - the distance a number is from zero

l-9l = 9

Scientific Notation and standard form is a way to make really big and very small numbers easier to read. When an exponent is postive it is a big number when it is negative it is a very small number and the number IS NOT negative.

1.7 x 10^{6 }= 1,700,000

6.23 x 10^{-10 }= .000000000623
