I am guessing BODMAS stands for Brackets, (I don't know), Division, Multiplication, Addition, and Subtraction. In the U.S.A. we use PEMDAS. PEMDAS stands for parentheses, exponents, multiplication or division, addition or subtraction. Just because the A comes before the S in BODMAS doesn't mean always add before subtraction. To help them with this put the word "or" between the letters "D" and "M", and "A" and "S." Tell them that when you solve the problems in the brackets or parentheses, do the exponents or what the "O" stands for. Then, ask them to find the first multiplication or division problem from left to right and solve it. Next, find the other ones and solve them. Last, they do the same thing, but with addition and subtraction problems. I hope this helped.
