People that do not understand the concept of 'BODMAS' are a pet hate of mine. For the previous page example of 40 + 40 x 0 + 1, there are no brackets (B), there is no 'of' (O), there is no division (D), there is a multiplication (M) which is then carried out FIRST (40x0=0), there are elements of addition (A) then used (equation becomes (FOLLOWING THE INSERTION OF THE 'M' SECTION) 40 + 0 + 1) = 41. There are no subtractions (S). It is that simple. Follow that methodology and there are no issues. 'D' & 'M' hold the same level of importance so BODMAS can also be considered as BOMDAS. They are equal.
