1.

a] -5,65 + [-2,08] - 1,35 =

b] 6,51 + [-2,775] - 11,125 =

c] - 10/9 + [- 1/6] + 9 3/4 -[-6,25]=

d] -9,3 -[- 12 1/5 ] - [72,8 - [ -13,002]] =

Answer 1

a] -5,65 + [-2,08] - 1,35 = -9,08

b] 6,51 + [-2,775] - 11,125 = -7,39

c] - 10/9 + [- 1/6] + 9  3/4 -[-6,25]=14,72

d] -9,3 -[- 12  1/5 ] - [72,8 - [ -13,002]] =-56,898

Answer 2

a] -5,65 + [-2,08] - 1,35 =-5,65-2,08-1,35=-9,08

b] 6,51 + [-2,775] - 11,125 =6,51-2,775-11,125=-7,39

c] - 10/9 + [- 1/6] + 9  3/4 -[-6,25]=-10/9-1/6+39/4=-40/36-6/36+351/36=305/36=8 17/36

d] -9,3 -[- 12  1/5 ] - [72,8 - [ -13,002]] =-9,3+12,2-72,8+13,002=2,9-72,8+13,002=-69,9+13,002=-56,898

Answer 3

A) =-5,65-2,08-1,35=-9,08

B)=6,51-2,775-11,125=-7,39

C)-1,(1)-0,1(6)+6,75+6,25=11,74 c)nie jestem pewny tego przykladu

D)-9,3+2,4-85,802=-92,702
