Raspunsurile sunt subliniate. Nu am stiu ce punct sunt, asa ca am pus asa. Sper sa fie bine! Sport la treaba!

Explicație pas cu pas:

Primul punct:

6×4×14+(275+142)×13-56×(142-96)=

=6×4×14+417×13-56×46=

=336+5421-2576=3181

Al doilea punct:

3 x (18 + 12 x 3) + (47 - 32) × 12 + 172 – 138 =

=3×90+15×12+172-138=

=270+180+172-138=

=450+34=484

Al treilea punct:

248 x (6 + 15) - (172 - 29) ×13 +63 x (5 + 2 x 8) =

=248×21-143×13+63×56=

=5208-1859+3528=

=3349+3528=6877

Al patrulea punct:

5 × 678 – 2 x (13 + 14 x 3) - (243 - 16 x 2) x 17 =

=5×578-2×81-454×17=

=2890-162-7718=
