The text covers all the topics of a first course in linear algebra. There is discussion on set theory, complex numbers and proof techniques. Complex number are mentioned very early in the text although not used.
I'm taking linear algebra at my university (as an undergrad), and I am having some trouble with it. I do just fine with the computational problems but when it comes to the proofs, I have some difficulty. As the title states, should an essentially introductory course in linear algebra require students to prove not only the central definitions.
However, there are several topics missing that I would consider part of a standard first course in linear algebra. Matrix factorizations, such as the Cholesky factorization, or decompositions, such as the LUD decomposition, do not appear to be treated.
This book contains a standard set of topics one would expect to see in a first semester Linear Algebra course, beginning with systems of linear equations and transitioning into vectors and matrices. Abstract vector spaces appear in the middle of... read more

Linear algebra is hard. Linear algebra is one of the most difficult courses that most STEM majors will study in university. Linear algebra is not an easy class because it is a very abstract course and it requires strong analytical and logical skills.

Calculus is, according to Wikipedia, “ … the mathematical study of continuous change, in the same way that geometry is the study of shape and algebra is the study of generalizations of arithmetic operations.” BUT, don't give up all hope if you need this class for your degree.
It is possible to teach yourself linear algebra. Some components of this field are more complex and lead us to machine learning; the basics are easy to grasp, even without help. Handling simple equations and finding unknown variables is the foundation of linear algebra and can help you get started.
Calculus is not a prerequisite for Linear Algebra.
A straight linear algebra course probably won't have any calculus in it, but different math departments will do different things with their course sequence(s).
Calculus 3 or Multivariable Calculus is the hardest mathematics course. Calculus is the hardest mathematics subject and only a small percentage of students reach Calculus in high school or anywhere else. Linear algebra is a part of abstract algebra in vector space.
So I know calculus 2 is usually considered the hardest class among non-engineering math. I've also read many opinions that linear algebra is relatively easy compared to calculus 2. However, I'm finding in my case that linear algebra is harder for me to grasp and feel comfortable that I understand 100% of the concepts.
As an entering student, you will probably go into Calculus II, then Linear Algebra, followed by Calculus III. Or perhaps Calculus III followed by Linear Algebra. The courses 401 (Abstract Algebra) and 405 (Analysis I) are the only two courses absolutely required for all majors.

If you are familiar with Algebra of Matrices, and a bit of set theory, then you can start learning Linear Algebra.
I quite liked Shilov's Linear Algebra, but it may be a bit dense. As others have said, calculus is not a prerequisite for linear algebra, but be prepared to refer to a math dictionary (or Wikipedia) on occasion if you go for Shilov. It can get a little dry.

There is a considerable overlap between Greub's Linear Algebra text and Roman's but in my opinion Greub takes a little more effort to read. In his multilinear algebra text, however, you will find topics that are rarely covered elsewhere. Unfortunately, it is out of print but Google here is your friend.
I have great news! You do not really need any calculus to begin studying linear algebra. You do need to understand functions and high-school level algebra to start learning linear algebra. As you progress higher through linear algebra, you could hit a level where dot products get replaced by generalized inner products, and you will deeply wish for the ease of only relying on real and complex spaces - but that's relatively advanced, and there is plenty of material that relies only on skills obtained in high school.
Now, while Axler is very good and gives you a firm grounding in the basics, it is not comprehensive. If you really like linear algebra and want to dive deeper, you might want to explore Roman's Advanced Linear Algebra. It is quite a bit more advanced than Axler and presupposes much more mathematical maturity, although technically it is self-contained. I think once you digested everything that's in Axler though you would be in a position to start looking at it.
A First Course in Linear Algebra, originally by K. Kuttler, has been redesigned by the Lyryx editorial team as a first course for the general students who have an understanding of basic high school algebra and intend to be users of linear algebra methods in their profession, from business & economics to science students.
Each chapter begins with a list of student learning outcomes, and examples and diagrams are given throughout the text to reinforce ideas and provide guidance on how to approach various problems. Suggested exercises are included at the end of each section, with selected answers at the end of the textbook.

This chapter describes linear functions. A function is a rule associating to each object from a certain set of objects called the domain of the function . Functions from R1 to R1 are functions that associate to each real number another real number. Functions from R2 to R1 are the functions of two variables: such a function associates to every pair of real numbers [ x, y] a real number f ( [ x, y ]). Functions from Rn to R1 are just functions of n real variables with real functional values. A function from Rn to Rm is a function whose domain is Rn and whose functional values are also vectors but in Rm. A linear function is a function f that associates to each vector in a vector in Rn a vector in Rm in such a way that for every two vectors v and w in Rn and every number a, f ( v + w) = f ( v) + f ( w) and f ( av) = af ( v ).
A subspace of Rn is a set S of vectors in Rn with the following properties: (1) whenever x and y are vectors in S, so is x + y; and (2) whenever x is a vector in S, so is ax for every scalar a. If u1, …, ur are vectors in Rn, the set of all linear combinations of them is called the subspace spanned by u1 ,…, ur. The set {u 1 ,…, u r } is called a spanning set of this subspace. If a subspace S of Rn is spanned by r vectors but cannot be spanned by fewer than r vectors, S has dimension r or is r -dimensional. Any spanning set consisting of exactly r vectors is called a basis of S. The chapter also presents the definitions of linearly independent vectors.
The easiest way to specify a plane geometrically is to specify a vector perpendicular to the plane and one point on the plane. The chapter presents a situation in which a vector ν is perpendicular to a certain plane and there is a point P0 = ( x0, y0, z0) on the plane. If P is on the plane, then the vector P0P is in the plane and, hence, is perpendicular to ν. Conversely, if P0P is perpendicular to ν, then P0P lies in the plane and so does P. The most convenient way of specifying a line is to give one point P0 on the line and a nonzero vector ν parallel to the line.
This chapter focuses on quadratic forms. A quadratic form in n variables is a polynomial function of x1 …, xn that is homogeneous and of second degree. It is a sum of monomials of the form axpxq ( p, q = 1, 2,… n ). When p = q, a square term is gotten of the form axp2; the other terms are cross-product terms. If q is a quadratic form in n variables x1 ,… xn, the matrix of q is the matrix ( apq) where app = the coefficient of xp2 in the polynomial and a pq = half the coefficient of xpxq in the polynomial. To each quadratic form from Rn to Rn, there corresponds a symmetric linear function f from Rn to Rn.
18.06 is intended for engineering and business majors, while the other two are for math majors, and are more heavy on proofs. Definitely check out the exams for 18.700 (the ones for 18.701 are kind of weird and have a substantial focus on group theory stuff too).
If the class is part of the math curriculum, then there's no problem with a proof based first course in linear algebra. Linear algebra is (usually) the first real proof based math course, after perhaps an intro to logic and proof, so it is common for students to struggle with the proofs. If you are having trouble following them in class, so you don't know how to approach assigned problems, read the proofs in the book until you understand it then try to reproduce it yourself. If you are having trouble with intuition, just keep on doing more problems.
