BODMAS

Didn't it used to have a different name? BIDMAS?

I got taught BODMAS/BIDMAS at school!

[Me. I Am Salman]

bidmas/bodmas - I swear it just stands for adding/subtracting etc.
Basic stuff, ytf do they feel the need to teach an analogy

The Answer is 20 - I am not wrong. Anyone that says otherwise is a ******.

[Roy Mars III]

how did you get 20

[Patrick]

5 + 5 + 5 - 5 + 5 + 5 - 5 + 5 x 0 = ?

Start at 5, add another 5 and another 5 = 15

Take away 5 = 10

Add 5, and another 5 = 20

Take away 5 = 15

Add a final 5 = 20

Times it by nothing = 20

If it were all to be multiplied by zero it would have to look like this

(5 + 5 + 5 - 5 + 5 + 5 - 5 + 5) x 0

There's a bit about it on here (yes, I know it's wiki, but I cba searching the net for a better source):

Timesing anything by zero equals zero. It'd only be 20 if you were timsing it with 1.

lol patrick

-It has suddenly dawned on me that my Math's teacher clearly knows nothing-

Going to start a row on this tomorrow morning.

[Ninastar]

if anything timesed by 0 is 0, then why isnt the answer zero?

Because BODMAS. You times 5 with 0 before doing the rest of the sum.

[Ramsay]

because of the BODMAS rule
so for this sum you gotta do 5 x 0 first which is 0..then you do 5 + 5 + 5 - 5 + 5 + 5 - 5 which is 15

[Samuel.]

-acting smart by paraphrasing Ben-

[CharlieO]

Why can people not do maths. Basically, you just do all the times and divide bits of a sum before the rest unless brackets are involved. tres simple.

[Samuel.]

Most of us haven't done it in years. And it's very rare that you actually need to use these techniques so it's easily forgotten.

[Novo]

What is the point in maths.. who created this ****

[Ramsay]

i didnt even learn this in school just found out from facebook because for ages i would pick the wrong answer then started coping on

[GypsyGoth]

Stupid sum

I thought that this was only when there was brackets involved

this.

[Ramsay]

I thought if there was brackets involved the answer would be 0 but since there isnt we do is that way ^ ?
