2.1 – Integers & The Number Line Numbers such as 3 (read “positive three” or just “three”) and 3 (read “negative three”) that are the same distance from 0, but on opposite sides of 0, are called opposites. Zero is its own opposite. The set of integers consists of the whole numbers and their opposites. On the number line, the positive integers are to the right of 0, and the negative integers are to the left of zero. Zero is neither positive nor negative. Definition The set of integers consists of the positive integers, negative integers, and zero. ... 4,3,2,1,0,1,2,3,4,... We use the symbol < to mean is less than. For example, 6 8 means “6 is less than 8.” The symbol > means is greater than. For example, 2 4 means “2 is greater than 4 .” The symbols > and < are called inequality symbols. A mathematical sentence that contains an inequality symbol is called an inequality. Example 1 – Insert the proper symbol, < or >, to get a true statement. a. 8 128 d. 14 814 b. 13 713 e. 10 5 10 c. 5 75 f. 4 11 4 The absolute value of a number is its distance from 0 on the number line. We use the symbol n to represent “the absolute value of n.” The absolute value of a number is either positive or zero. Example 2 – Find the absolute value. a. 3 b. 3 c. 0 L11 – pg 57 (11, 15, 19, 23, 29 & 43-51 odd) d. 27
