I remember always being confused with the whole BEDMAS thing as a kid - especially when they told us that the division and multiplication could be switched, as well as the addition and subtraction. It wasn't until late in high school that I figured our why.
Is it possible that the OP is incorrect? The teachers could be saying, do the multiplication/division from left to right, or do the addition/subtraction from left to right. I was told something to that effect when I questioned the system. The reason? No reason, it just shuts the kid up, and won't make a difference.
Interesting to see the acronyms that different cultures / generations come up with - PEMDAS, BEDMAS, BIDMAS, BOMDAS, etc. I imagine it's geographical area, though, not really the decade. Perhaps the parentheses / brackets, what with computers becoming much more common in the last few decades. Programming (at least currently) depends heavily on the use of brackets, and it's less of a mouthful than parentheseseses.

Here, you use parentheses for the first level, then brackets for the second level. For example, in solving functions: A function of f(x)=7+u in an equation of (X+17)^2+2x+10=0 would basically result in an equation of: ([7+u]+17)^2+2(7+u)+10=0. notice the position of the brackets in comparison to the parentheses. lol, and this is the simple stuff. Yay math!

To be honest, we mostly call them brackets, even the parentheses. Perhaps they thought it was too much for us to wrap our tiny minds around. Obviously, brackets within brackets are done before brackets containing brackets. ({[Inception!]})

Depending on what kind of math you're doing, definite brackets (the {} brackets, IE, curly brackets) have different uses. Mostly I see it used to enclose and define sets.

I'm begining to wonder if this is an example of "lies to kids".
That is, if they are being taught left to right to get them used to sequential calculations, get them happy and them hit them with the horrors that is BEDMAS!
Many thanks for the responses though!

Wait a minute, what the feth is this sh*t about Triceratops? What moron of a palaeontologist thought this up? Having seen both compared, there's nearly no evidence, and seems to be mostly conjecture. It's untrue unless the Triceratops suddenly adopts the proportional growth rate of a small rodent.

I said five, because I was taught BIMDAS, and to the best of my knowledge that's still what is being followed. I don't really get the level of superiority in this thread though, from people who think BIMDAS or any other acronym like that is the way maths must be. If maths was taught left to right it wouldn't suddenly get dumber or less capable of describing anything. It'd still be maths, it's just the form of notation would change.

“We may observe that the government in a civilized country is much more expensive than in a barbarous one; and when we say that one government is more expensive than another, it is the same as if we said that that one country is farther advanced in improvement than another. To say that the government is expensive and the people not oppressed is to say that the people are rich.”
