Prealgebra (7th Edition)

a) 110 - 80 = 30 b) 3(-9 + 11) = 6 c) $\frac{24}{-6}$ = -4
a) "The difference of 110 and 80" means 110 - 80. The difference of 110 and 80 is 30 means 110 - 80 = 30. b) "The product of 3 and the sum of -9 and 11" means 3(-9 + 11). That amounts to 6, which makes the equation 3(-9 + 11) = 6. c) "The quotient of 24 and -6" means 24 divided by -6, or $\frac{24}{-6}$. That yields -4, which makes the equation $\frac{24}{-6}$ = -4.
