Trabajando en clase

Nivel básico 6. Resuelve:

1. Calcula: R = (–7)(8) – (–9)(5)
T = (–8)(3 )+ 13
Resolución:
T = (–8)(3) + 13 7. Resuelve:
T = (–5)(3) – (–4)(–4) – 14
T = – 24 + 13
T = – 11
Nivel avanzado
2. Calcula: 8. Calcula:
A = (–5)(–3) – 10 M = (–8 –2) (–3 + 1) –14
Resolución:
3. Calcula: M = (–8 –2) (–3 + 1) –14
M = –4 –(–6)(–3)
M = (–10) (–2) – 14
4. Calcula: – . = +
–
R = (–2)(–3)(–4) – 16 M = + 20 – 14

Nivel intermedio M = + 6 o 6

5. Resuelve:
B = (–7)(2) – (–5)(–4) 9. Calcula:
Resolución: Q = (–2 + 6) (–3 – 4) + 6
B = (–7)(2) – (–5)(–4)
–
+
– . = – – . = +
B = –14 – (+20) 10. Resuelve:
+
– . = – A = (–3) (7) (–4) (–5)
B = – 14 – 20 = – 34
