Question

efectuati: 7-2, +5+(-8), -5-6, -8-(-8), -6-9+5, 12+5, 12+(5-17+1), -(12-4-2)+46, 45-46+(-6+2), 6-(5+9-4)+9​

Answer 1

Răspuns:

Explicație pas cu pas:

7 - 2 = 5

____________

+ 5 + (- 8) = 5 - 8 = - 3

____________

- 5 - 6 = - 11

____________

- 8 - (- 8) = - 8 + 8 = 0

____________

- 6 - 9 + 5 = - 15 + 5 = - 10

____________

12 + 5 = 17

____________

12 + (5 - 17 + 1) = 12 + (- 12 + 1) = 12 + (- 11) = 12 - 11 = 1

____________

- (12 - 4 - 2) + 46 = - (8 - 2) + 46 = - 6 + 46 = 40

____________

45 - 46 + (- 6 + 2) = - 1 + (- 4) = - 1 - 4 = - 5

____________

6 - (5 + 9 - 4) + 9 = 6 - (14 - 4) + 9 = 6 - 10 + 9 = - 4 + 9 = 5
