Bonjour

1) 5×(-7)+6×(-11)÷2

= - 35 - 66 : 2

= - 35 - 33

= - 88

2)7×[6-4×(-7)]

= 7 x (6 + 28)

= 7 x 34

= 238

3)-9+6×(-7)

= - 9 - 42

= - 51

4)-13+15

= 2

5)-8+5×(-9)

= - 8 - 45

= - 53

6)-3+4×(-6)

= - 3 - 24

= - 27

7)-45÷(-9)+3×(-11)

= 5 - 33

= - 28

8)17+8×(-8)-36

= 17 - 64 - 36

= 17 - 100

= - 83

9)-4+(6-27)÷3​

= - 4 - 21 : 3

= - 4 - 7

= - 11.

Bonjour,

1) 5×(-7)+6×(-11)÷2

= -35 -66/2

= -35 -33 = -68

2)7×[6-4×(-7)]

=7*(6 -28)

= 7*  - 22= -154

3)-9+6×(-7)

= -9 -42 = -51

4)-13+15

= +2

5)-8+5×(-9)

= -8 -45 = -53

6)-3+4×(-6)

= -3 -24 = -27

7)-45÷(-9)+3×(-11)

= 5 -33 = -28

8)17+8×(-8)-36

= 17-64-36 = -83

9)-4+(6-27)÷3​

-4 - 21/3

= -4 -7 = -11
