"7 + 7 / 7 + 7 x 7 - 7=?

Using bodmas,

7/7=1. 7*7=49

7+1+49-7= 50.

Its easier when I write it out!

The absence of brackets makes it 50, though I can see why some people imply the brackets when it's written in print.

Interestingly they don't call it BODMAS nowadays, but BIDMAS. The 'I' standing for 'indicies'.

In my day the 'o' stood for 'of', then it became 'order', bloody progress...

Was helping my ten year old last night when I noticed this.

How many people do you reckon can remember "the formulae" for simultaneous equations? We always got told you don't have to remember it, as it will be given to you. BANG!!! In it went. Never to be forgotten.

Sorry prof. I know your way cleverer than me on most thing but on this you're wrong.

If no brackets you should use B - Brackets (), {} or []

O - Of (similar to multiply)

D - Division /

M - Multiplication *

A - Addison +

S - Subtraction -

Which gives 50, as had been shown.

BID or BOD, makes no difference there are only two types of mathematical operation.

MULTIPLICATION: This includes division (which is just an inverted multiplication) and indexes or of (which is just many multiplications)

ADDITION: This includes subtraction (which is just a negative addition)

The actual or for doing any equation is Multiplication them Addition. The order of operations with in the two groups actually does not matter.

Finally, if we really want, we can actually reduce the number of mathematical operations to one as Multiplication is just many additions.

So, the long and short of it is, all that time they spent teaching you arithmetic at school they wasted because they never told you the simple truth. The only thing you can ever do with numbers is add them and nothing else.

Isn't addition just a negative subtraction?

That's not quite working left to right though.

Working left to right would be

(((((7+7)/7)+7)×7)-7) =

((((14/7)+7)×7)-7) =

(((2+7)×7)-7) =

(9×7)-7 = 63-7 = 56

The answer giving zero requires addition first, then division, then multiplication, (or multiplication then division), then subtraction, which is just weird.

probability of throwing exactly 2 sixes in 3 throws...

Long time since I studied this but off the top of my head...

In 3 throws there are 6x6x6 possible outcomes, so 216 possibilities.

There are 15 combinations with 2 6's

6 6 (1-5)

6 (1-5) 6

6 6 (1-5)

So 15 chances in 216.

Something is niggling at me though so that could well be wrong.

Using similar logic for at least 2 6's

Three throws = 6x6x6 = 216 possibilities

6 6 (1-6)

6 (1-6) 6

(1-6) 6 6

18 possibilities with at least 2 6's.

18 chances in 216

You have a 1 in 6 chance of throwing a 6 on each attempt. You have 3 attempts. So,in my messed up brain I'm multiplying those chances. I'm stuck now

Without BODMAS it would be

I'm assuming that 7/7 means 7 over 7 otherwise known as 7 divided by 7 which equals 1. The sum therefore is

7+1=8

8+7=15

15x7=105

105-7=98

Rules of maths haven't changed for thousands of years. BODMAS/BIDMAS/BEDMAS isn't new.

Most people are taught basic maths very badly.

The answer is 50.

Parentheses can be used to change the arithmetic priority of parts of the expression.

It's arithmetic, not maths. As has been said above, it simply resolves down to addition. There are only ten digits, 0 to 9 , how hard can it get?

The sad part is, as with the matter of parentheses (brackets) or "two sixes" question, many many schools/teachers are dreadful at setting questions carefully and accurately.

Nice but when written correctly as

------

3 * 2

----- * 2

then you can see clearly that multiplying 12 by 2 and divide by 3 is the same as 12 divided by 3 and then multiplied by 2, unlike the first one which is a completely different equation.

So, always working from right to left:-

12/3*2 = 12*2/3 = 2/3*12

As long as 3 is the divisor the order does not matter. For any other answer you require brackets.

that way you'd just get lines that get closer together and it'll be not as obvious. Here, you see the fractions 12 and 14 in their "standard shape", so what remains must obviously be 14. Then, put the same shapes inside the remaining square which is of the same proportions as the initial one (and it's easily checked that 12·14=18); you'll get the next smaller square, hidden deeper in the corner. Repeat, and the square will shrink to a tiny dot (not a whole line, which may intuitively seem larger

Sorry I misread the second part of the example, with only 1 die the rule for rolling at least one 6 in any number of rolls is 1-(5/6)x N (when N is the number of rolls) so with three rolls the probability of at least one 6 from 3 is 91/216.
