I have got an assignment headed "Rules of Order" in which there are a few thing I am not sure about, so this is what I have done.
Problem:- 15-12÷3X2=
I assume the rules of BIMDAS apply so I did this:- 15-12÷6=
Then 15-2= 13.
Next problem:- 50-5-10X2=
so I did this:- 50-5-20=
then:- 45-20=25
Am I on the right track here?
Thanks.
What you did was dividing 12 by 6.
But this would mean that it was 12÷(3X2).
Whereas here, we have : 12÷3X2, which is the same as 12X2÷3
The order is (-, +) after (X, ÷)
Parenthesis are here to define other orders. For example in 12÷(3X2), it means that you do the multiplication first, so that you have 12÷6. But it's true if and only if there are parenthesis.
