An expression could refer to a saying. Have you ever heard anyone say "Oh, it's an expression."? That is basically saying not to take it too literally, it is just a saying. For example,"it's raining cats and dogs". This is somewhat like a math expression. A math expression is an equation - without the equal sign. For example, 8k + 4 or 3 / 33. There are certain rules for different expressions depending on what it is composed of. This is like a (saying) expression in that it is different for different situations.

Expression can also refer to facial expression.

temperature, coordinates in geography, academic ranks, difference between notes in music, burns, severity of crimes, degrees of Freemasonry (a fraternal organization), and of course the largest degree of the monomial terms of a polynomial.

These are all related in one important way: they rank something by size or importance.

The standard form of a polynomial is like ordering from high to low. Except instead of Emma books and movies, you are ordering monomial terms (by degrees)

In biology, there are several plants and animals who are symmetrical. Examples are: sea anemones, sea urchins, jellyfish, sand dollars, apples, some flowers, and... butterflies!

This is a polynomial because it fits the criteria:

A polynomial can have constants, variables and exponents, 
but never division by a variable or a negative exponent

Although it is not good and is discrimination, us humans sometimes see power or money instead of the actual person when we look at somebody. We see the outside... but not the real person.
