Substitution code breaker – brackets, indices and fractions

Substitute the values into the expressions, checking the correct order of operations to deal with single brackets, powers and fractions. The hidden message is a rather lovely Maths joke!

Sorry, didn't explain that well at all.
I meant to say it's not the sheet at fault, its just that some students got themselves confused by the first calculation in the way I mentioned above because they they were unsure of the concept of dividing by 0 so ended up using the code instead of the given value. Just worth checking they have that concept secure.

VERY CONFUSING FOR STUDENT
Had a problem with this. Some of the calculations use the values for a, b,c and d given at the very top of the page but some use the values in the code instead:
11c/a uses c= 2 and a = 0 from code to get 22 (W)
ab-8 uses a = 5 and b=3 from the top values given to get 7 (H)
