27-18 + (- 7) - 32 1 / 3 + (- 1 / 5) + 1 + 20 / 3 + (- 1 / 4) - (- 2.75) + 1 / 2 The mixed operation of (- 2 / 3) + (- 1 / 6) - (- 1 / 4) - 1 / 2 to calculate rational numbers
27-18 + (- 7) - 32 = 27-18-7-32 = 27-7 - (18 + 32) = 20-50 = - 30; 1 / 3 + (- 1 / 5) + 1 + 2 / 3 = (1 / 3 + 2 / 3) + 1-1 / 5 = 1 + 1-1 / 5 = 9 / 5; 0.5 + (- 1 / 4) - (- 2.75) + 1 / 2 = 1 / 2-1 / 4 + 2 + 3 / 4 + 1 / 2 = 1 + 2 + 2 / 4 = 7 / 2; (- 2 / 3) + (- 1 / 6) - (- 4)
