Question

Can someone with a good heart help me please

Answer 1

`1)9-8=1\\2) 10(9+8)=170\\3) (13+7)/(2) =10\\4) (9(6)+30)/(6) =14\\5)2(9)+4=22`

for the next question i'm not sure but here is what i understand:

biggest size we solve it by the first equation so it will be
`132=(2d)/(3) +3 \\d=193.5\\`

and the smallest it will be by the second equation
`132=(d)/(4) -3 \\d=540`

Explanation:

for the fist question: just instead of the a write 9 and c write 9 and so on

just remove the alphabet and put the number
