what’s the physical meaning of mathematical operations?

1.06K views

Let’s say you have a division. You’ve got 3/2, where 3 might be acres and 2 might be brothers so from there you could deduce that the division just means that the 3 acres of land will be distributed between two brothers. Summation and multiplication are quite straight forward, but what the hell does one do with multiplication and exponentiation? If I got 20 N-m of torque, wtf does the multiplication tells me there? If something follows a square root?

Please feel free to add any other operations to these. Thanks!

There is no physical meaning, in the sense you seem to be using, for mathematical operations. They’re just a way to use two concepts to indicate a third; as such, they only apply to ideas. Those ideas can be mapped onto physical situations in turn.
