c) 222:2*4+[92+2*4*(29-14" 2:7)*0]+100=
va rog frumos

Answer 1

a) [(10-2*3)*4-5]+217+29
= [ ( 10 - 8 ) x 4 -5 ] + 246
= ( 2 x 4 -5 )+ 246
= ( 8 - 5 )  + 246
= 249

b) 72+2*(652:2-26)+[12*3*5+(24*3+72)*0]-10
= 72 + 2 x ( 326 - 26 ) + [ 36 x 5 + ( 72 + 72 ) x 0 - 10
= 72 + 2 x 300 + 180 - 10
= 72 + 600 + 170
= 672 + 170
= 842

c) 222:2*4+[92+2*4*(29-14" 2:7)*0]+100
= 111 x 4 + [ 92 + 8 x ( 29 - 28 / 7 ) x 0 ] + 100
= 444 + [ 92 + 8 x ( 29 - 4 ) x 0 ] + 100
= 444 + ( 92 + 200 x 0 ) + 100
= 444 + 92 + 100
= 636
