Answer 1

2) (+43 – 27 +32) : (-23 +57-42) =

( 16+32):(34-42)=

48:(-8)= -6

3)-2·[+7.+47 – 19-26)-58] – 76 =

-2•[7•(28-26)-58]-76=

-2•(7•2-58)-76=

-2•(14-58)-76=

-2•(-44)-76=

88-76=12

4)-10-1-3 •[-316-3. (+231–344 + 115)-(-79+ 83 – 54) - 56]} =

-11-3•[-316-3•(-113+115)-(4-54)-56]=

-11-3•(-316-3•2+50-56)=

-11-3•(-316-6-6)=

-11-3×(-328)=

-11+984=973

5) + 550 • (-5•(+146–374 +135) : (+281- 374 +124) – 125) =

550•[-5•(-228+135):(-93+124)-125]=

550•[-5•(-93):31-125]=

550•(465:31-125)=

550•(15-125)=

550•(-110)= -60500

6) rescrie operatiile ca sa o pot rezolva

7) (+3)•(-3):(-3)-(-5)•(+5):(-5) =

-9:(-3)-(-25):(-5)=

3-5=-2
