Question

[(3+2)×3-3+3×(3+3:3)]:3-3×3+3:3×1+3:1​

Answer 1

Răspuns:

[ ( 3 + 2 ) × 3 - 3 + 3 × ( 3 + 3 : 3 ) ] : 3 - 3 × 3 + 3 : 3 × 1 + 3 : 1​

= ( 5 x 3 - 3 + 3 x 4 ) : 3 - 3 x 3 + 3 : 3 x 1 + 3 : 1

= ( 15 - 3 + 12 ) : 3 - 3 x 3 + 3 : 3 x 1 + 3 : 1

= 0 : 3 - 3 x 3 + 3 : 3 x 1 + 3 : 1

= 0 - 3 x 3 + 3 : 3 x 1 + 3 : 1

= 0 - 9 + 1 x 1 + 3

= 0 - 9 + 1 + 3

= - 5
