10. –4· (–2–3) – 1=
11. 63:(4+5) – 4·(5–3) =

Answer 1

Respuesta:

-(-3) . ( -3) = +3 . -3 = -9

6.4. (4-2) = 24. 2= 48

7. 25:5 - 1 = 7. 5 -1 = 35 - 1 = 34

8. -3. (-2) . (-1) - 6:3= -24. -2. -1 - 2 = +48 . -1 - 2 = -48 - 2 = -50

9.-5. (-12+4) = -45 . -8 = +360

10. -4 . (-2-3) -1 = -40. -5 -1 = 200 - 1 = 119

11. 63 : (4+5) - 4. (5-3) = 693 : 9 - 4 . 2 = 77 - 8 = 69
