CHAPTER 1 BASIC ALGEBRAIC OPERATIONS Numbers The numbers —3 and 14 are integers. They are also rational numbers since they can be written as a and Las 1 3 is an integer, rational (7) , and real. V—4 is imaginary. fee sy : meer ne is irrational (because 7 is an irrational number) and real. 6 <8; 6 is to the left of 8. SO LaLa ge hoa a ag BANS Oy shy tO -4<-|-3|; 4 is to the left of -|-3| . (-|-3|=-G)=-3). Vv a, then (a) b-a isa positive integer. (b) a—b is a negative integer. (c) b-a : ree. the numerator and denominator are both +a positive, but the numerator is less than the denominator, so the answer is a positive rational number than is less than 1. (a) If x>0, then x is a positive number located to the right of zero on the number line. x : es
