Integers 6 3 So what is an integer

Integers 6. 3

So what is an integer? Set of whole numbers (this includes zero) and their opposites {…-3, -2, -1, 0, 1, 2, 3…} An integer and its opposite are the same distance from zero on a number line The opposite of -4 is 4… both are 4 spaces from zero

Positive Integers are… 5 1 greater than zero. 2 4 3 1, 2 Negative Integers are… -5 -1 4 3 , 2 -12 less than zero.

Zero is… an integer that is neither positive nor negative! Zero does not have an opposite!

Is that number an integer? -3 15 -2. 4 0 Yes N 0 0. 5 Yes N 0 -19 Yes N 0 4 Yes N 0 -123 Yes N 0

Absolute Value is… number is the distance of a number from zero on the number line regardless of direction. Absolute value is represent by the absolute value bars EX:

Ordering Integers When ordering integers, smaller numbers are always to the left of larger numbers on the number line. The further left a number is on the number line, the smaller the number! Quick Vocabulary: Ascending- least to greatest Descending- greatest to least EX: -15 is smaller than -5 because -15 is to the left of -5!

Click the right answer! Which number is the smallest? -13 -23 -3 8 20 0 Which set is ordered from least to greatest? -15, -8, -3 0, -2, -4

Comparing Integers You see the small part 1 st! You see the largest part 1 st! I always eat the largest number!

Another way to remember… < This looks this . The arrow points to the smallest number! If arrow tip points left…you say “less than”! > This looks this Remember: The . arrow points to the smallest number! If arrow tip points right…you say “greater than”!
