That is excellent.  Thank you Rosala.  I don't like texting on the phone much either. 

No Stu, you are doing uni maths.  You should be able to do the maths to show that number and not just copy it from another site.

Yes, that is exactly right Chris.

You can never assume in mathematics that something is so unless you can prove it!

You can have 3 points too Chris - yours is the best answer so far although with a little work I think Stu's answer would be better. 

Great - It's been lonely around here - DragonSlayer made sure we didn't get too lonely.

I bet he has missed the rest of the 'rat pack'!

Heaps of really cool stuff!!

Lots of stuff to do with rates of change and areas and volumes. (complicated ones)

Calculus is brilliant!

Rosala is back!

Stu I expect your answer is the better intuitive approach but you have not shown where 1.619 came from.

So your 'proof' is only the germ of an idea.

No my approach was similar to yours only I had a page of Latex which I lost.

Without doing any maths it appears obvious that it will not be possible.

I'm sure that Alan will come up with a much more intuitive logic as to why this cannot be.

I do not intend to redo mine.

I just proved that this was impossible but the whole lot got delted on me.

I hate it when that happens!   

Good evening Sasini,

Multiply and divide are equally important  and the multiply comes first so that is the one that should be done first. 

It actually won't make any difference to this answer but technically that is how it is.

$$50*6/10-6+36\\
= 300/10-6+36\\
=30-6+36\\
=24+36\\
=60$$
