Question

Calculeaza tinand cont de ordinea operatiloe. 6x4+14(275-142)x3-156-36)= 3x(18+12x3)+(47 -32)x12+172-138= 248x(6+15)-(172-29)x13+63x(5+2x6) = 5 678-2x(13+14x3)-(243-16x2)x17=

Answer 1

24+14x133x3-156-36=24+186x3-156-36=24+
558-156-36=582-156-36=426-36= 390

3x (18+36)+15x12+172-138=3x54+180+172-138=
162+180+172-138=342+172-138=514-138=376

248x21-143x13+63x(5+12)= 248x21-143x13+63x17=5208-1859+1071=3349+
1071=4420

5628-2x (13+42)-(243-32)x17=5628-2x55-211x17=5628-110-3587=5518-110-3587=5518-3587=1931
