order? how does that make sense? brackets alright ig

Order is often used to describe exponents when talking about functions and other mathematical properties. In a lot of cases, it's also equivalent to a degree. For example, a function y = x² - 9 is a second-order/degree polynomial.

Alternatively, one could find a second-order rate of a reaction, which means the rate of reaction is proportional to the square of a solution's concentration.

Order of magnitude? Thinking out loud.

You have the right idea, and you are right in some regards. Generally the order of magnitude is an order of 10. That is, 1350 could be represented as 1.350×10³, so the order of magnitude is the third order of 10, which is 10³ (i.e. some value x×1000).

Order of magnitude?

It's actually short for "to the order of", as in 2 squared is 2 to the order of 2. i.e. same thing as Exponent or Index.
