1. Hi TSR. Yet again, maths makes me want to stab someone.
Anyway.
Was doing a maths mock paper. According to the mark scheme 5-2(m-3) can be expanded to 11-2m

How does this work? Would love it if someone very kind and, er, paitent could explain this to me

thanks a lot
2. Ignore the 5 at first, and simply expand -2(m-3) out.

Which makes -2m-6

how do I get 11 from that?
4. You forgot that two negatives multiply to give a positive, resulting in -2m + 6

OH. I gotcha.

Thank you.
