19. (a-b)/d...a = -2, b = 3, c = 6 and d = 1/3 (-2 - 3) / (1/3) = -5/(1/3) = -5 * 3 = -15 <== 20. -a(b + c) =    -2(3 + 6) =     -2(9) =      -18 < ==     22. (a - b + 3d)/b       (-2 - 3 + 3(1/3) / 3 =       (-5 + 1)/3 =        -4/3 <=== 23. b - a^2       3 - (-2^2) =       3 + 4 =       7 <=== 25. ab^2 =       -2 * 3^2 =       -2 * 9 =      -18 <=== 26. -(b-c)^2       - (3 - 6)^2 =       -(-3)^2 =         -9 <==
