davenportram Posted February 15, 2011 Share Posted February 15, 2011 (3x3 + 3) /3 BODMAS, don't forget. Sorry Gboro They call it BIDMAS now. (Bracket Indices Divide Multiply Add Subtract in that order) It confused me when my little one started talking about it, made me feel old Just edited my post because I misread the question. You could do it this way too: 3^(3-3)+3 (where ^ means to the power of) =3^0+3 =1+3 =4 Link to comment https://dcfcfans.uk/topic/5615-maths-question/#findComment-136170 Share on other sites More sharing options...

Perky1106 Posted February 16, 2011 Share Posted February 16, 2011 Maths was never my strong point. No idea how I scraped a B. Link to comment https://dcfcfans.uk/topic/5615-maths-question/#findComment-136172 Share on other sites More sharing options...
David Posted February 16, 2011 Share Posted February 16, 2011 Amazing the stuff they teach you at school that you never use after you walk out the gates at 16. Can't even remember doing that, although I do remember a scientific calculator was needed at the time, now all I use is that calculator on the start menu on me laptop.
