The Maths Thread

Enjoyed solving this one:

Wonder how many marks you’d get for this if you said X=5 because of the 3,4,5 triangle rule.

Haven't read the thread so maybe missed this but isn't it the square root of the the other 2 sides added together to give the hypotenuse which is then square rooted? So 3 squared = 9, plus 4 squared = 16. So hypotenuse must be the square root of 25 = 5.

Yes, but once you know the 3,4,5 rule, it saves you working it all out.

6,8,10.
9,12,15 etc

Haven’t read through the whole thread, but has anyone mentioned Mathler.com
It’s like Wordle but for maths.
Keep you going for 5 minutes a day.

You are Pythagoras and I claim my £5.

Some clever people on here, I worked for William Hill from 1980 and until settling machines arrived I spent all my afternoons working out bets, there were quite a few cuts and tips to save time. I used to hate 8/11 and 8/13, they were hard to break down, as an example the former was:

Two thirds of the stake plus an 11th of the two thirds

However whilst able to work out odds, probabilities and market’s Geometry is a total mystery to me, just can’t get my head around it, I think you have to be double clever to understand that and other complex maths.

I loved Geometry and trigonometry, algebra on the other hand…. Not so much

Surprised there wasn’t a chart for those odds. Would have saved you all a fair bit of time.
