There is no such thing as "Straght" in math: the word does not [yet] exist in the English language. It is not easy to define "staright". You start off with a set of primitive mathematical concepts and then define other concepts using them. A straight line is a primitive geometric concept: it is the shortest distance between two distinct points in a plane. [You will probably need to use the concept of straight to define shortest!]
It means negatives
Zero
"key concept" is not a mathematical term . A key concept is an important idea. Two key concepts in math are derivatives and integrals of functions. ( "function" is also a key concept.)
A math concept is how you solve a math problem or the ideas. You usually have to memorize math concepts.

The most important math concept is the idea of zero.
A math CONCEPT is a fancy way of describing the different ways and things you can and can't do in math. A math Concept can be 5!. That in term equals 5*4*3*2*1, which then = 120.

nope math is real, but is an abstract concept
