What is 5 + 3 * 0?

[splodgeyAl 10]

What other rules of operation are there?

The one that say 6 customers buying a bun and a coffee each pay a different amount to 6 customers buying a coffee and a bun each, or that a bun and a coffee for each of six people is a different price again!!

1. 6

3. 8.75

4. 17.5 what happened to question 2?

 

Willman is of the opinion that BODMAS does not apply to examples with no brackets. The very site he linked to disagrees with him. I posted the specific questions which show him to be wrong.

 

Congratulations on getting all three questions wrong.

 

1. A, 7

3. D, 20

4. C, 18

So, if I think about this as 6 customers buying a coffee and bun, we have:

 

6 x 1.05 + 3.50, which is £9.80!!!

 

Three versions of the same sum - three different answers because BODMAS does not apply?

 

Honestly - one can only laugh!

 

It get's even worse if you have 6 coffees and 6 rolls ordered in that order :-

6 x 1.05 + 6 x 3.50 = 6.30 + 6 x 3.50 = 12.30 x 3.50 = 43.05

The answer to the op is still 0.

If you don't want to believe it or would prefer to ridicule or find fault please feel free.

 

If brackets aren't there,then they don't exist so BODMAS does not apply. If its on a page discussing BODMAS it should be common sense that BODMAS will apply wouldn't you think?

As are all the "trick" questions posed.

I guess someone had better tell every database vendor they need to re-write their maths engine?

 

select 5 + 3 * 0;

+-----------+

| 5 + 3 * 0 |

+-----------+

| 5 |

+-----------+

Although he now seems to be saying they apply to those questions, because even without the brackets, you can still apply the BODMAS rules if the question is written on a page about BODMAS. Is that right Willman?

 

Even the questions which are on a completely different site and don't mention BODMAS anywhere on the page, but I'm guessing that's besides the point...

And Excel:

 

Input "=5+3*0" Result = 5

My 14 year old just informed me the answer is indeed 5, due to Bidmas « Brackets, indices, division, multiplication, add & subtract

Willman - can you please find and link to a written example of a sum where:

a) brackets are not implied (like in your shop example)

b) addition / subtraction and multiplication / division are included

c) BODMAS does not apply

[willman 10]

And Excel:

 

Input "=5+3*0" Result = 5

 

Using a formula in excel places brackets around the sum,making it follow BODMAS.

[alchresearch 214]

At school I was taught to read it as:

 

5 plus the sum of 3 * 0.

No it doesn't.
