Integers, Absolute Value & Exponents! Refresher… Integers – Integers are all the whole numbers and all of their opposites on the negative number line including zero. 7 opposite -7 Opposite Numbers – Numbers that are the same distance from zero in the opposite direction -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 https://www.youtube.com/watch?v=6xv2bP xXWKw Absolute Value – The size of a number with or without the negative sign. The absolute value of 9 or of –9 is… 9. Negative Numbers Are Used to Measure Temperature Negative Numbers Are Used to Show Debt Let’s say your parents bought a car but had to get a loan from the bank for $5,000. When counting all their money they add in -$5,000 to show they still owe the bank. Replace each () with >, <, or = to make a true sentence. 1. 4 () -4 2. 5 () |-5| 3. -6 () -12 4. |-34| () |-9| Definition of Exponent An exponent tells how many times a number is multiplied by itself. Base 2 2 Exponent Location of Exponent An exponent is a little number high and to the right of a regular or base number. Base 3 4 Exponent What an Exponent Represents An exponent tells how many times a number is multiplied by itself. 4 3 =3x3x3x3 How to read an Exponent This exponent is read three to the 2nd power or three squared.
