Explicación paso a paso:

a) 5 + 3 = 5×4 + 4×3 = 20+12

4 4 4×4 16

32 = 2 . 1 = 2×1 = 2 = 1

16 1 6 1×6 6 3

b) 2 - 5 = 2×6 - 9×5 = 12-45

9 6 9×6 54

-33 : 4 = -33×3 = -99 = - 11

54 3 54×4 216 24

c) 11 : 5 = 11×2 = 22 = 11

6 2 6×5 30 15

11 - 7 = 11×25 - 15×7 = 275-105

15 25 15×25 375

170 = 34 = 0.453

375 75

d) 3 - 5 = 3×6 - 8×5 = 18-40

8 6 8×6 48

- 22 = - 11 : 4 = -11×3 = -33

48 24 3 24×4 96

-11 + 2 = -11×9 + 32×2 = -99+64

32 9 32×9 288

- 35 . 27 = - 35×27 = -945

288 9 288×9 2592

= -105 = - 35 = - 0.364
