1. 10 - 6 + 8 = 12
2. 10 - (6 + 8) = 10 - 14 = (-4)
3. 10 - (5 x 6 ) = 10 - 30 = (-20)
4. (10 - 5) x 6 = 5 x 6 = 30
5. 8 x 7 - 6 = 56 - 6 = 50
6. 8 x ( 7 - 6 ) = 8 x 1 = 8
7. 24 : 6 x (-2) = 4 x (-2) = -8
8. 24 : ( 6 x (-2)) = 24 : (-12) = (-2)
9. -12 + 4 : 2 - 8 = -12 + 2 - 8 = (-20) + 2 = -18
10. ( -12 + 4 ) : 2 - 8 = (-8) : 2 - 8 = -4 - 8 = -12
11. 11 - 8 : 4 - 10 = 11 - 2 - 10 = 9 - 10 = (-1)
12 ( 11 - 8 ) : ( 4 - 10 ) = 3 : (-6) = (-0,5)
13 3/4 - 5 x (2-7) = 3/4 - 5 x (-5) = 3/4 - (-25) = (-25 i 3/4 )
14 4 - ( 3 - 1.5) x 2 = 4 - 1.5 x 2 = 4 -3 = 1
15 nie wiem
Odpowiedź:
1. 12
2. 10-14=-4
3. 10-30=-20
4. 5×6=30
5. 56-6=50
6. 8×1=8
7. 4×(-2)=-8
8. 24÷(-12)=-2
9.-12+2-8=-18
10. -8÷2-8=-4-8=-12
11. 11-2-10=9-10=-1
12. 3÷6=3/6=1/2
13. 3/4-5×(-5)=3/4+25=25i 3/4
14. 4-1,5×2=4-3=1
15. 3i 3/8×1/3+1=27/8×1/3+1=9/8+1=2i 1/8
