Question 1168758:  This question is a bit unusual but I don’t have anyone else to ask. I study math as a hobby and some books are expensive so I bought a used book called University Calculus: Early Transcendentals (2nd Edition). Now I think I might have wasted my money because I see there is calculus 1, 2, and 3. I can’t figure out if this book is 1, 2, or 3 or is it something else? I saw the same publisher offers 2 other. Oops with almost the same name as this one but one says “single variable “ and the other “multivariable”. I guess my question is which level book do I have and which books come after this one?

All students / (and everyone student)  start/(starts)  learning  Calculus from one single variable.
You did not waste your money;  in opposite,  you are one step now from entering the beautiful world of  Calculus  (!)
Many exiting discoveries wait for you on your way  (!)
Happy learning  (!)
The next book after that is a  "Multivariable Calculus".
