McDonalds Australia is providing this free online maths tutoring program http://www.mathsonline.com.au/ It is intended for high school students (although I have registered my son who is not yet at high school) and is based on "Australian state curricula for Years 7 - 12".

If nothing else, it is interesting to see the level of difficulty for each of the year groups. (I'm sure coolerking will enjoy the explanation of BIDMAS/BODMAS given by the tutor to year 7/8).

Tried the demo and I quite like it, there did appear to be a lack of a basic formula for pythagoras missing from it which to me is a fundamental error but maybe I am being picky.

It's a cross between mathswatch videos and mymaths in the uk.

Remember, it's BIDMAS

Not according to the tutor on the program - hence my comment .

If you buy a Big Mac meal costing $7.99 and took the supersize option, at an additional $1.50, followed by a second course of a McFlurry at $2.99, how much change would you get out of $20? (remembering to round up, or down, to the nearest 5 cents).

Not necessarily.... it's all relevant to the country. What's BIDMAS to you is BEDMAS to me. I'm a math teacher and for me (in Canada) it's always been BEDMAS.

Brackets
Exponents
Division
Multiplication
Addition
Subtraction

I see in the UK they use the term indices instead of exponents.

Acronyms

In the United States, the acronym PEMDAS (for Parentheses, Exponentiation, Multiplication/Division, Addition/Subtraction) is used as a mnemonic, sometimes expressed as the sentence "Please Excuse My Dear Aunt Sally" or one of many other variations. Many such acronyms exist in other English speaking countries, where Parentheses may be called Brackets, and Exponentiation may be called Indices, Powers or Orders. Also, as Multiplication and Division are of equal precedence, M and D may be interchanged; and Of (see example 3, above) is equivalent to Multiplication. With respect to the latter operators, it is usually best to simply work from left to right. This also applies to Addition and Subtraction on most occasions. Thus, we also have BEDMAS, BIDMAS, BIMDAS, BIODMAS, BODMAS, BOMDAS and BPODMAS.


So it's not wrong, just different. So if Australia is using BODMAS then I gather they use the terms Brackets and Order (instead of indices or exponents).

So, what is the answer to 10 - 3 + 2 ?

using any of BEDMAS, BIDMAS, BIMDAS, BIODMAS, BODMAS, BOMDAS or BPODMAS

Addition comes before subtraction yes ? so do we add 3+2 before doing the 10-5 subtraction = 5 ?

or just do 10-3 (subtraction first) then addition aferwards, 7+2 = 9

What I was referring to is the fact that in the McDonalds program they are using BODMAS with the explanation that the "O" is there simply to assist in saying the word as it is difficult to say BDMAS without this additional letter. There is no mention of order, indices or exponents.

Thank goodness the till works this out automatically - our local McDonalds gets thrown into total confusion simply by asking for a Big Mac with no cheese.

Well, the 'O' in BODMAS when used by some teachers in the UK means 'of'. Usually because it is being taught to primary school children. But the 'I' obviously has equivalents. As I teach in a school with a strong Jamaican influence, I always say that the 'I' is where the fish live (bad Jamaican accent), "In da seas"...

You know ABC

Ten take 3 plus 2

so 3 + 2 is actually, -3 + 2

HW
Use 2, 4, 6 and 8 once and only once
and
the operations +, -, X or /

Make 25.

I hadn't gotten that far into the site. I didn't bother once I saw you needed to create an account. Free or not I only wanted a quick look so I didn't bother. My daughter is only 5 so won't be needing it anytime soon!

But yes, for kids I can see why the exponents is left out. But it should certainly be included in the older grades 7-12 or so.

And how many hours would you need to run to shed the lard?

I have never met so many numerically challenged people in my life than in Aus.
