# quantity in math

##### Junior Member
How should I imagine the quantity? I visualize it as something continues that's why I guess I found it a lil complex.

May anyone please instruct me how should I visualize/analog the quantity of something in math?

Quantity is how many you have. For example: I have 3-$5bills, I have 7 bananas, I owe you 3 oranges, I have 9x's etc... #### Ryan$

#### Ryan$##### Junior Member You put amounts in quotation marks but are defining quantity. But that is OK. something that equals a collections of other things then I start imagine that their "amounts" are related to each other and they are not separated. I am not exactly sure what their means but I will try to address your concerns. I think by their you really mean to use a singular proverb not plural. I guess you are thinking about something like x =$17.50y + $33z, where x is your total salary, y is the number of hours you worked at$17.50/hr and z is similarly defined. Yes, x is an amount! Its units are dollars. x IS relates to y and z. It is possible that y and z are separated but they are related to x. If you earn $17.50/hr and your mate earns$33/hr and your hours at work never cause any problems, then y and z are not related.
VERY meaningful!! helped me alot thanks!!!

another thing in the same concept, lets assume a pressure of something is defined as quantity ; so sometimes in order to find a pressure of specific thing we should do superposition of other things ! and this trick doesn't ring in my mind always ... so I guess it doesn't ring always because I miss the concept of the term "superposition". ( I mean with superposition like this X=x1+x2+x3+x4+x5+x6 )

if you clear up the term superposition by analogous to be remembered in my mind and thank you in advance.

Can you please provide an example of this phenomenon?

Please note that this is at least the 2nd time we asked this student to define/give an example of superposition.

I didn't notice before.
