Explicație pas cu pas:
2+2×[2+3×(2+202÷2)]= 626
= 2+2×[2+3×(2+101)]=
= 2 + 2×(2+3×103) =
= 2 + 2 × (2 + 309) =
= 2 + 2 × 312 =
= 2 + 624 =
= 626

[(8×7)+244] ÷100= 3
= ( 56 + 244 ) : 100 =
= 300 : 100 =
= 3

82 448 - [236×7+(116+380)÷8]= 80 724
= 82 448 - ( 1 652 + 496 : 8 ) =
= 82 448 - ( 1 652 + 62 ) =
= 82 448 - 1 724 =
= 80 724
