Question

5.- Resuelve la siguiente operación combinada. 6 × 7 + 39 : (11 − 2 × 4) =
42 + 39 : ( 11- 8)=
42 + 39 : 3=
42 + 13 = 55

48 : 6 ⋅ [15 − (6 + 3)]
8 · (15 – 9) =
8 · 6 = 48

[12 − 3 ⋅ (17 − 4 ⋅ 3)] + 15 − 4 ⋅ 3
[12 – 3 · (17 – 12)] + 15 – 12 =
[12 – 3 · 5] + 3 = 12 – 15 + 3 = 0


21 − (16 −11) · 2 + (8 + 5)
21 – 5 · 2 + 13 =
21 – 10 + 13 =
34 – 10 = 24
