And as promised, the more later post...

Ok, those of you know me will realise that for many years I worked in technology education, and pretty much everyone will have heard of the recent push for STEM subject education (science, technology, engineering and mathematics).

Where am I going with this?

Well, the forums are an excellent source of engineering and technology info, there is even bit of science from time to time....

But dear friends, I noticed we are light on maths. Hence today's quick math quiz.

Consider:

If I have 13 assorted sump bolt washers in my spares drawers, and need only one to be the right size, but have already been once to the automotive store,

1) express as a probability the odds that none of the buggers fit
2) express as a percentage how pissed of I was to discover this
3) express as a distance how far I had to walk on my second trip to the automotive parts counter

And for extra credit,

4) express as a fraction how much more superstitious I am now than I was due to their being 13 in the drawer

Other than that, it's not been a bad day, oil and coolant done, clutch ready to go in and belts sat on passenger seat waiting to go on probably tomorrow.

1) Very
2) 100%
3) It could be 2 or 4 miles: you failed to frame the question correctly. Was your first trip 2 miles there & back or just there?
4) Can superstition be fractional, you are either ten tenths superstitions or you're ten tenths not.
13 is one up from 12 & one down from 14 & half of 26. It's also a prime number, all numbers are magic, 13 is no more magical than any other, mind you Pi's pretty cool.
It's been a nice day for a walk, I only wish I'd been able to get out with the roof down: commitments!

You overlooked the simple algebraic approach:

2x (original trip)

And using n as a fractional progression, to state an unknown increase within a range of 0 and 1


... But that's a solid B+

Ah well no better than when the pedagogery were trying to educate me.

Changed the fob battery...polished bodywork..

Toyo T1R proxes X2 ordered, fitted Friday.

Other than 2x wipers yet to be sourced, I believe this. Brings a temporary close, no... Pause.... To the saga of pre MOT hysteria.

Got the rear subframe under the car.

MOT pass today and no advisories again! Whooohooooo

I'm not sold on the colour, looks darker than i wanted, but will do now as it was only a quick job.

Thanks In between the rain i managed to sort my center caps, and lean a wheel against the car, colour is growing on me now, 2 wheels done, two to go.
