32. 17 – 44

33. –12 –16 + 18

34. 23 – (–11) – 30

35. 19 + (–54) – 7

36. –21 + 6 – (– 40)

37. –2 –5 – (–7) + 6

38. 5 – 12 + (–13) – (–7)

39. –3 –4 – (–5) + (–6) + 7

40. 2 – (–6) – 10 + 4 + (–11)

41. $\frac{2}{9}-\frac{7}{9}$

42. $\frac{5}{12}-\left(-\frac{1}{16}\right)$

43. $\left(-\frac{3}{8}\right)-\frac{1}{4}$

44. $2\frac{1}{2}-\left(-3\frac{1}{4}\right)$

45. $6\frac{9}{16}-13\frac{1}{16}$

46. $\left(-\frac{5}{6}\right)-\left(-\frac{2}{3}\right)$

47. $\left(-2\frac{3}{4}\right)-5\frac{5}{6}$

48. $\left(-1\frac{7}{8}\right)-\left(-3\frac{1}{6}\right)$

49. 6.5 – (– 2.7)

50. (–0.275) – 1.375

51. (–86.4) – (–22.9)

52. 0.0025 – 0.075

53. 22.75 – 36.45 – (– 54.72)

54. (–7.35) – (–4.87) – 3.66

55. $3\frac{1}{2}-6.6-\left(-2\frac{1}{4}\right)$
