Hi Remada,
I am going to illustrate how I would show my work with a different example. I am going to simplify
9  5[ 4 ÷ (2)  15] 3
I know that I ned to start inside the brackets and find 4 divided by 2 and then subtract 15 from this result. Next I multiply this by 5 and then by 3 and finally subtract what I have from 9.
Here goes
9  5[ 4 ÷ (2)  15] 3
= 9  5[ 2  15] 3
= 9  5[ 17] 3
= 9  (85) 3
= 9 
(255)
= 9 + 255
= 264
Now try your problem,
Penny
