Do we get to control the order of operations using parentheses?

well randanll u have to use ur brains a bit harder.. its a simple mathematical equation..
well if u guys give up i can give u the answer

Hi Sona:
6 / ( 1 - 5 / 7 ) = 21 !

great don ... thats the right answer

a fairly similar one with
1 4 5 6 --> get 24

2 + 2 = 5
*Consult your nearest copy of 1984 for the answer.

I think I've got it. I had the parameter list all wrong! I'm missing an argument of type NoamChomskyQuote. Let's see here...

5*6-1-7=24
This is well kown as "Computing 24", is a very popular game for kids in china (at least when i was in element school).
