Obliczcie w kolejności wykonywania działań ; a)9-8-7-6-5             b)9-(8-7-6-5)          c)9-(8-7)-(6-5)         d)9-[8-(7-6-5)]       e)9-{8-[7-(6-5)]}      f)9-[(8-7)-(6-5)] z gury dzięki ;)

a)9-8-7-6-5 = -17 b)9-(8-7-6-5) = 9-( - 5 - 5 ) = 9 - ( - 10 ) = 9 + 10 = 19 c)9-(8-7)-(6-5) = 9- 1 - 1 = 7 d)9-[8-(7-6-5)] = 9 - [ 8 - ( - 4 ) ] = 9 - 12 = - 4 e)9-{8-[7-(6-5)]} = 9 - { 8- [ 7- 1 ]} = 9- {8 - 6} = 9- 2 = 7 f)9-[(8-7)-(6-5)] = 9- [1 - 1 ] = 9   liczę na naj ;)  

a) 9-8-7-6-5=-17 b)9-(8-7-6-5)=9-(-10)=9+10=19 c) 9-(8-7)-(6-5)=9-1-1=7 d)9-[8-(7-6-5)]=9-[8+4]=9-12=-3 e) 9-{8-[7-(6-5)]}=9-{8-[7-1]}=9-{8-6}=9-3=6 f) 9-[(8-7)-(6-5)]=9-[1-1]=9
