I am Noah Webster –

they named the

dictionary after me.

Since I wrote the

first dictionary, I know how important defining

words is. Get crack-a-

lackin’!!!

Today, you are going to get the

definition and some examples of each word.

With all this help, you won’t forget.

No worries guys!! Hakuna

Matata!!!

Definition: All numbers that exist

Example: {π,-91.82, 28, -12, ½, 84.56, 45.2394…, 57, …}

How will I remember? – To remember real numbers, just think of all the numbers that you know.

Definition – ____________________ that can be expressed as a fraction

Examples –

How will I remember? – Rational numbers include fractions, terminating decimals, repeating decimals, and integers

Definition – ______________________ that are positive or negative and that DO NOT include fractions and decimals

Example – {-4,-3,-2,-1,0,1,2,3,4, …}

How will I remember? – Integers include all rational numbers except fractions and decimals.

Definition – All _____________ zero and greater

Example – {0,1,2,3,4,5,6,7,8,…}

How will I remember? – Whole numbers are all positive numbers starting with zero

Definition – All _____________________ NOT including zero

Example – {1,2,3,4,5,6,7,8,9,…}

How will I remember? – They are called “counting numbers” because that is how you count.

Definition – _____________________ that cannot be written as a fraction.

Example –

How will I remember? – Irrational means “crazy” (like me!). So that means that irrational numbers are the crazy decimals that never end and that don’t have a pattern to them

Numbahs are VERY

important for you to know.

Wait … what is a perfect square again?

Perfect squares are the numbers that result from “squaring a number” (taking a number to the 2nd power)

Example – {1,4,9,16,25,36,49, 64,81,100,121,144,169,…}

We are related as father and son. How are these numbers
