Question

a) 16 ÷ ( - 2 ) – ( - 4 + 2 ) + 5 · ( - 1 ) = sln -11

b) 8 – 6 ÷ ( - 3 ) + 4 · ( - 2 ) + 5 · ( - 10 ) = sln -48

c) 4 – ( - 5 + 2 ) – 15 ÷ ( - 5 ) + 4 · ( - 2 ) = sln 2

d) 2 + ( 8 ÷ 4 ) – (- 2 · 3 ) + 9 ÷ (- 3 ) = sln 7

e) 8 ÷ ( - 4 ) – ( - 5 – 3 ) + 3 · 2 = sln 12

f) 4 · 14 ÷ (- 2) + 9 · ( - 3 ) – 2 ÷ (- 2) = sln -54

g) 3 – 4 ÷ (- 4) + 4 · ( - 4 ) – 1 = sln -13

Answer 1

Respuesta:

a) 16÷(-2)-(-4+2)+5•(-1)

-8-(-2)+(-5)

-10+(-5)= -15

b) 8-6÷(-3)+4•(-2)+5•(-10)

8-(-2)+(-8)+(-50)

10+(-8)+(-50)= -48

c) 4-(-5+2)-15÷(-5)+4•(-2)

4-(-3)-(-3)+(-8)

7-(-3)+(-8)= 2

d) 2+(8÷4)-(-2•3)+9÷(-3)

2+2-(-6)+(-3)

4-(-9)= -5

e) 8÷(-4)-(-5-3)+3•2=

(-2)-(-8)+6

(-10)+6= -4

f) 4•14÷(-2)+9•(-3)-2÷(-2)

(-28)+(-27)-(-1)

-28+(-28)= -56

g) 3-4÷(-4)+4•(-4)-1

3-(-1)+(-16)-1

4+(-17)= -1
