Answer 1

Răspuns:

a) -12

b) 43

c) -27

d) 666

Explicație pas cu pas:

a)

-52: (19-32)-2-[18+44: (-11)] =

= -52: (-13)-2-(18-4)

= 4-2-14

= -12

b)

[25-24:(11-14)]-[-9+8:(27-35)] =

= [25-24:(-3)]-[-9+8:(-8)]

= (25+8)-(-9-1)

= 33-(-10)

= 33+10

= 43

c)

(-3):(-3)* (12-3²)-2[4² +11:(-11)] =

= 1*(12-9)-2(16 -1)

= 3-2*15

= 3-30

= -27

d)

10²-10:10 (15-14)" +3[5³-(-2²)³] =

= 100-1*1 +3[125-(-4)³]

= 100-1 +3[125-(-64)]

= 99 +3(125+64)

= 99 + 3*189

= 99 + 567

= 666
