max   13 #97 Posted March 13, 2012 1.05 + 3.50 x 6  What the answer?  Not trick but a day to day sum.  22.05 - no trick, basic maths.  1.05 + (3.50 x 6) = 22.05  Do you see, do the multiplication first then the addition. Share this post Link to post Share on other sites Share this content via...
dosxuk   10 #98 Posted March 13, 2012 The page is discussing BODMAS it states it clearly. It calcualtes the brackets out first follow the exercise through and not isolate each as individual calculations.  Are you reading the same page as us?

willman   10 #101 Posted March 13, 2012 Are you reading the same page as us?  Yep the one that says BODMAS at the top. That gives a hint what is being discussed.  as i said if you think i'm wrong, calculate you're next shopping bill and see. Share this post Link to post Share on other sites Share this content via...

I can only hope that your not teaching English comprehension as well as maths.  Question 1, from bottom of page.  What is the value of 3 + 6 ÷ 3 × 2 ?  A. 7 B. 6 C. 4 D. 1.5  If you answer anything other than A then you really shouldn't be teaching maths.  jb Share this post Link to post Share on other sites Share this content via...
willman   10 #104 Posted March 13, 2012 Which would be written mathematically as (1.05 + 3.50) x 6  And if it was written that way bodmas would apply, but it wasn't and its still mathematically correct. Share this post Link to post Share on other sites Share this content via...
