Explicație pas cu pas:
Buna!
1) 2 · ( -6 ) · ( -1 ) = -12 · ( -1 ) = 12
2) 5 · 7 · 0 · ( -3 ) = 35 · 0 · ( -3 ) = 0 · ( -3 ) = 0
3) 6 + 6 · ( -2 ) = 6 + ( -12 ) = - 6
4) -3 + 4 · ( -5 ) = -3 + ( -20 ) = - 23
5) 16 : ( -4 ) = - 4
6) -10 : | - 2 | = -10 : 2 = - 5
7) ( -2 ) · ( -6 ) : ( -3 ) = 12 : ( -3 ) = - 4
8) 7 - [3 - (10 - 15)] = 7 - [3 - (-5)] = 7 - (3 +5) = 7 - 8 = -1
9) -14 : ( -2 ) + 3 · ( -4 ) = 7 + 3 · ( -4 ) = 7 + ( -12 ) = -5
10) ( -9 + 3) · ( -3 + 2) = ( -6 ) · ( -1 ) = 6
11) -8 + 20 : ( -5 ) = -8 + ( -4 ) = 12
