I'm making NO claim about the evaluation of any advanced software other than a recognition of implicit multiplication; hence the reference to 'Googling'.
Here's a tip for people new to Maple or to 2-D input: always use a space for implied multiplication. 2-D math input in Maple allows for implicit multiplication, which is writing a multiplication operation without an explicit multiplication operator.

The TI-89 family, TI-92 family, and the Voyage 200 recognize implied multiplication...

Re: Evaluation of 6÷2(1+2)

Try avoiding ambiguous notation in queries. Instead of
For either of these, there is no confusion as to what this means. To see how W|A interprets the order of operations, see:
In my years of number crunching for the military, NO ONE writes equations in this form '6 / 2(1+2)'. We use that funny little bar ___ in ALL expressions with a numerator/denominator.
I wanted to answer the question AS QUERIED and make NO claim beyond that. I will say, I have NEVER had a calculation submitted for final approval/inclusion rejected or altered for algebra errors.
I find the intensity of the conversation illuminating & appreciate the sincerity of the respective authors without umbrage!
