Chapter 1 Section 3 Real Number Classifications Comparing Real Numbers

The Real Numbers Irrationals: unending and non-repeating decimals … … Rationals: can be written as a fraction Integers: positive and negative whole numbers Wholes: naturals including zero Naturals: counting numbers

Let’s try some classification! Tell me how each number can be classified (hint: they can fit into more than one category) …

Comparison Symbols Less than Greater than Less than or equal to Greater than or equal to Remember, the alligator always wants to eat the bigger number!

Compare Some Which is greater? There are two ways… Get a common denominator Turn both into a decimal

Let’s give it a shot! Put the numbers in order from least to greatest Two techniques: either turn each fraction into a decimal get a common denominator and compare the numerators

Absolutely only one more thing… Absolute Value: the distance a number is from zero The positive version of x whether it started off as positive or negative

Practice Please Find the absolute value of each
