Thank you for your reply. I have tried both websites. As you say the first one
does not have the "ambiguous" case that is with "-" and "+", while the second
one, it does have a question that shows the "right" way to deal with "-" and
"+" signs.
I believe the "BOMDAS" applies with the following clarifications. When
"operations" of same strength, then the "left to right" rule applies.
Multiplication and division are of same strength. While, addition and
subtraction are of same strength.
Though the "order of operations" is simple, it is the foundation of the advance
maths. It is very important to ensure students will not be misled.
Thank you.
Kelvin
