yeah they dowhen it's easy to read in normal written format. When a formula is written in a string however it becomes more difficult to determine which OoO takes precedent such as in this case, ie is it h - 32*t^2 all divided by 2, or is 32*t^2/2 subtracted from h?

Even when I am writing out formula with pen and paper I will often use () just to ensure there is no confusion....actually it might come from coding where I do the same thing as well.

No biggie, just thought I'd offer a suggestion for next time to ensure people get full marks on their homework
