Answer 1

Răspuns:

Explicație pas cu pas:

222 × 12 - ( 77 - 55) + 72 : 9 - 666 + ( 77×33) = 4 525

= 2 664 - 22 + 8 - 666 + 2 541 =

= 2 642 + 8 - 666 + 2 541 =

= 2 650 - 666 + 2 541 =

= 1 984 + 2 541 =

= 4 525

________________________________________________

222 x 12 = 222 x ( 10 + 2 ) = 222 x 10 + 222 x 2 = 2 220 + 444 = 2 664

77x33 = 77 x ( 30+3) = 77x30 + 77x3 = 2310+231 = 2 541
