My dad always used to ask me....how many beans make five.

Whole beans? Fraction of beans? Can you expand please so we can work on the answer :-)

Here’s a maths question - find a number between 10 and 99.
Reverse the digits and then divide your new number by 3 and it will be exactly 3 less than the number you started with.
What number did you start with?

27

Well done mate.

I'd be inclined to agree with your son.
Ho isn't a number nor does it have a numerical value.
If we take the word Ho as one word (and apply a numerical value to it of 1 as it is one word) then it would be correct as 1 cubed is 3.

1 cubed is 1.

My wife bought my son a tee shirt with a picture of Father Christmas and the text HO3, with the 3 in superscript text. We had a discussion yesterday whether the formula was correct or not.

Both me and my elder son thought the formula should be HO3, [or possibly (HO)3, 3(HO), 3HO]. My son, who is in year 2 studying maths at MMU said we could drop the brackets as the H and O were a single entity because each letter did not have a given distinct meaning or value. Fair enough.

He also argued that the formula was correct. We said it wasn't because it meant HO cubed, which wouldn't necessarily result in HO being said three times. He argued that didn't matter because HO was not a numerical expression.

All a bit confusing for me. Anyone able to shed any light on this? This picture shows the formula, but the model isn't my son, and it isn't the exact same shirt.

What is the probability of bumping a thread exactly one year to the day of its last posting?

Therein lies the problem, I don't know, never did and unfortunately never will......

I was always intrigued with the 'German Tank Problem' and it's use in WW2, and it's accuracy compared to conventional intelligence.

Did it keep you awake at nights, Yes, Good.......................

True story, an old colleague of mine at the Bookmakers William Hill got sacked, prosecuted and jailed for stealing 8k in the mid 80’s (was a substantial amount then).

Whilst he was in prison the Area Manager, a right old character Joe from Northern Ireland bumped into his Mrs in Stockport, he asked how she and the kids were coping, she said everything was ok but her husband was going back into engineering when he finished his sentence and he was allowed out to do a day release course (literally).

Joe said “that’s good, at least if he’s 8 thousand out he won’t get 2 years in jail”

1 cubed is 1.

So it is.
I'm blaming it on being an early morning post.
I'll change my answer then - ho cubed is wrong
