Răspuns :
-17+10+(-2)•5+10=-17+10-10+10=-17+10=-7
-15+10+(2)•5+10=-15+10-10+10=-15+10=-5
-15+10+(2)•5+10=-15+10-10+10=-15+10=-5
- 17 + 10 + ( - 2 ) x 5 + 10 = - 7
= - 7 - 10 + 10 =
= - 7
______________
Doar daca este - 15 in loc de - 17, obtii raspunsul variantei d
- 15 + 10 + ( - 2) x 5 + 10 = - 5
= - 15 + 10 - 10 + 10 =
= - 5
