the answer is 20. BEDMAS is just a way of remembering the order of operations. It always applies. If there are no brackets, look for exponents, if there are no exponents, then look for divisions, if there are no divisions, then look for multiplications, if there are no multiplications, then do additions, lastly you would do subatractions, if any.
so in this case it is as follows:
4 x 4 = 16 + 4 x 4 = 16 + 4 - 4x4=16 (multiplication always comes before addition or subtraction), then 16 + 16 = 32 + 4 = 36 - 16 = 20 (additions are always done following any multiplications and subtractions are always done following and additions). Order of operations never changes, despite what or what is not in the equation.
The state of education in the world today is scary, i wonder what the requirements are to pass mathematics in this day and age considering the number of people poorly skilled in math. I'm not even talking algebra or trigonometry which can be difficult to master. I'm just talking basic math. Stuff people learn in like grade five. It's getting very scary.
