Not at all.

If you don't show the work then you don't prove that you know anything at all about the process. You could be lucky (I can't count the number of times I've made two mistakes that canceled each other out.) or you could have cheated.


You're 16, so you're probably in grade 10, right? Give it a couple of years, and you'll probably have an epiphany about how important showing your work is.
