So what is the correct answer, & why?


How on earth did 26% of the people who responded think the answer was 13?

In my world, we have a sequence for performing the various calculations required.
Brackets, (powers) Of, Division, Multiplication, Addition, Subtraction. We were taught it as BODMAS. **

So, 2x4 = 8
8 + 2 = 10.

Some may claim that the process should be left to right, which gives 2 + 2 = 4, leading to 4x4 = 16. The people who claim this are wrong.

I have no idea how anyone gets an odd number as the answer.


** That Twitter thread refers to PEDMAS, which is just a new way of saying the same thing. Parentheses, Exponents, …

Morning all,

My 10 year old twins didn’t have any problem getting the correct answer of 10 but it’s taught in schools as BIDMAS now.

The I is indices.

He should never have done this interview. Makes about as much sense as the Prince Andrew interview.

"I went for a drive to see if I was safe to drive"

Why take your wife and kids if you're unsure if you're safe to drive?

Absolutely excruciating.

Chris Whitty is great. He's faced a solid two hours of questions and never faltered or sidestepped once.

Yes, he’s very, very good.

Grant Shapps very good too.

Tremendous performance KarmaDope !

Thank you Bergaroo

Are the units for question 9 metres and the units for question 10 seconds ?

Yes Lisa, they are. How’s Pete and the twins?

All well thank you David. We are taking the self isolation very seriously and none of us have left the house for over 2 weeks now.

Yes, I’m still losing pressure

Thank you again Tom.

I’ve undone the braided pipe on the right hand side. It is fully undone and a small amount of water dripped out. I can’t pull it off totally, probably because of the rigid part of the pipe on the other side. Is that good enough or shall I unscrew the left hand side which I think will enable me to then remove it ?

Ok, I think I understand now. The filling loop only needs to be connected during the filling process. So it can be disconnected as long as the taps are closed. Some say it should be disconnected as this prevents the water from the heating flowing back to into the mains if the valve fails.

So if I disconnect the filling loop and I no longer lose pressure then the pressure loss was due to the water flowing back into the main and the valve is probably faulty.

If the pressure loss continues then I have a leak

Tasks

Ok. So while the heating is on, I’ll fill to 1.5 bar and disconnect the right hand side of the filling loop. What am I expecting to happen or not happen ?

Thank you.
