Answer 1

Respuesta:

a) - 3 x 2 x 3 x 5: 10 + 32 + 17 x 5 - 16 x 4 - 100: 2 - 3 =

= - 6 x 3 × 5 : 10 + 32 + 17 × 5 - 16 x 4 - 100 : 2 - 3 =

= -18 - 5 : 10 + 32 + 85 - 64 - 50 - 3 =

= - 90 : 10 + 32 + 85 - 64 - 50 - 3 =

= - 9 + 32 + 85 - 64 - 50 - 3 =

= - 9

b) - 34 + 85 - 96 + (12-5) - (9+32-15) + (30 + 17 + 24) = - 34 + 85 - 96 + 7 - (26) + 71=

= - 34 + 85 - 96 + 7 - 26 + 71=

= 7

c) -( 400: 20 ) x 3 + 42 - ( 12:4) x 2 + 6 x ( 30 - 27) =

= - (20) x 3 + 42 -3 x 2 + 6 x 3 =

= - 60 + 42 - 6 + 18 =

= - 6

d) - 73-52 + 60 : 4 + 8 x ( 40 : 10 + 5 ) =

= -73 - 52 + 15 + 8 x (4+5) =

= - 110 + 72 = - 38

e)- (15:3+2) + 240 : 5 - 72 + 35 : 7 =

= - ( 5 + 2) + 48 - 72 + 5 =

= -7 - 19 = - 26

f)-( 9 x 10): 10 + 8 + 360 : 6 - 44: 4 =

= - (90) ÷ 10 + 8 + 60 - 11 =

= - 9 + 8 + 60 - 11 =

= 48
