Explicație pas cu pas:
( 16 : 8 + 7 ) × 5 = 45
= ( 2 + 7 ) × 5 =
= 9 × 5 =
= 45
_______________________
8 : ( 4 : 2 + 6 ) × 2 = 2
= 8 : ( 2 + 6 ) × 2 =
= 8 : 8 × 2 =
= 1 × 2 =
= 2
____________________
2 × ( 12 - 6 ) + ( 6 - 2 ) = 16
= 2 × 6 + 4 =
= 12 + 4 =
= 16
___________________
5 × 8 : ( 4 + 6 - 2 ) = 5
= 40 : ( 10 - 2 ) =
= 40 : 8 =
= 5
