What's the difference between"mean" and "average"
"Mean" has a precise mathematical definition (and in fact, there are several types) and you're very unlikely to hear it outside those contexts. "Average" is usually a colloquial term that usually means arithmetic mean, but can also mean "typical" or "neither good nor bad." More on reddit.com

May 2, 2021Precise meaning of Denote in Mathematics
There are things called "group representations". You take an abstract group, and find a group of matrices that is isomorphic under matrix multiplication. The matrix group is called a representation of the abstract group. For example the symmetric group S4 is represented by the group of 4x4 permutation matrices. There are representations of other things too. Take an abstract thing and find a more familiar thing that behaves the same way. More on reddit.com

October 3, 2017What is the meaning of 'value' in mathematics?
Value just means a definite mathematical object, which is to be contrasted with an indefinite object, most often called a variable. For example, we can interpret the equation 2x = 6 as describing something about the variable x. I haven't given the value of x, but we know something about it. Namely, when doubled, you get 6. From there you know you can figure out the particular value of x is 6/2 = 3. As another example, functions can be defined in terms of rules or formulas, which are specified in terms of operations to be performed on a variable. For example, f(x) = 2x is the doubling function. It just doubles whatever particular value for x you input. If x has the value of 4, then the doubling function assigns f(4) = 8. More on reddit.com
