Solvent: every job uses algebra. In fact every person uses algebra every day.

You go into a shop and buy products totalling X. You hand over a note worth Y. How do you work out what you should get back? With algebra. Your change should be Z = Y - X.

thinking math is man-made is probably why its your worse subject Lolwut? Of course it`s man made. Who else made it?

In prehistory we invented the natural numbers from counting on our fingers (which is why we use base 10). The ancient Egyptians and Greeks invented most of geometry. The Arabs invented algebra. Newton (or Liebniz, depending on your point of view) pretty much invented calculus.

The natural universe has no concept of Pythagoras` Theorem or the Fundamental Theorems of Calculus or that pi is 3.14159etc. These are entirely human constructs.

@almightybob, Seriously? Pi, and pretty much all other mathematical theorems, was discovered through OBSERVATION! It existed in the natural world, and thus we found it. Next you`ll be telling us the Golden Ratio is unique to renaissance paintings...

- No matter how tricky you are.

I have a black one just like this!

This book goes into great detail about the history of mathematics.
