this is probably quite simple but I'm still relatively new to learning math, have decided to enroll on a course a while ago (unfortunately it's now the weekend and I can't contact my tutor til Monday!)
I'm trying to get my head around what is happening on the following expression:
p = ns - ( f + nc )
My course materials say this can also be be written as:
p = ns - f - nc
However I was under the impression any numbers outside the brackets are multiplied by the numbers within the brackets, so say for simplicitiess sake..
p = ns(f + nc)
would result in:
p = nsf + n2sc
However with p = ns - f - nc, is that not the process of taking ns, deducting f from the result, and then deducting nc from that? Or is it instead the multiplication of ns * -f * -nc
Hope someone can clear this up for me!
