Mary buys x pairs of trousers except she has actually bought a kilt

kiltLet number of prs of trousers bought = x
If Mary has £60 and price of trousers=£12
How many prs of trousers can Mary buy
12x =60
6x=30
3x=15
1x =5

Usually we leave out the 1 and write x=5 QED

So Mary can buy 5 pairs of trousers.This is algebra
Is it sensible to buy 5 pairs of identical trousers? That is not mathematics.It might be common senses,ethics,foolishness or wisdom.
That is a more complex question like” buy 2 get one free” when you don’t even need one!

Further,should Mary draw her life savings out and buy 1,000 pairs of trousers?
Clearly not so where  should she draw the line? Because ladies get tired of their clothes and how long is Mary going to live? And she is depriving 999 other ladies of a pair of trousers as well.That is  worth thinking about but it’s not mathematics,is it.
From this we can conclude that  algebra is easier than other problems we deal with/Amen

No music

I’ve lost all  the music again.
Sabotaged by  the lack of a pen
I’ll  extemporize faster
With my brain in   dried plaster
If it sets, I’ll be perfectly Zen.

I broke my leg but it  wasn’t too bad
A leg never thinks or feels sad
My brain needs a glove
Of gentle, kind  love.
Is it me or is everyone mad?

I saw my old man on a bus
It was pulling away,how I cursed
I only glanced sideways
On the streets and the highways
I’m almost fatalistic or worse.
