What is linear algebra?
Linear algebra is the branch of mathematics that studies vectors, matrices and linear maps between vector spaces. It gives a common language for solving systems of linear equations, describing transformations such as rotations, and analysing data. It underpins engineering, physics, computer graphics, economics, statistics and machine learning.
- Matrices and systems: Gaussian elimination, rank and solutions of Ax = b
- Determinants and inverses: when a matrix is invertible and how to find the inverse
- Vector spaces: subspaces, span, linear independence, basis and dimension
- Linear transformations: kernel, image and matrix representations
- Eigenvalues and eigenvectors: diagonalisation and applications
- Inner products: orthogonality, Gram–Schmidt and least squares

Worked example: solving a system by Gaussian elimination
Solve x + y + z = 6, 2y + 5z = −4 and 2x + 5y − z = 27.
| Step | Row operation | Result |
|---|---|---|
| Eliminate x from row 3 | R3 → R3 − 2R1 | 3y − 3z = 15, so y − z = 5 |
| Use row 2 and the new row 3 | From y − z = 5, y = z + 5; substitute into 2y + 5z = −4 | 2z + 10 + 5z = −4, so z = −2 |
| Back-substitute | y = −2 + 5 | y = 3 |
| Back-substitute | x = 6 − y − z = 6 − 3 + 2 | x = 5 |
| Check in the original equations | 5 + 3 − 2 = 6; 6 − 10 = −4; 10 + 15 + 2 = 27 | All satisfied |
Worked example: determinant and inverse of a 2 × 2 matrix
Find the determinant and inverse of A = [4 7; 2 6] (rows separated by semicolons).
| Step | Working | Result |
|---|---|---|
| Determinant | det A = 4 × 6 − 7 × 2 | 10, so A is invertible |
| Swap and negate | Swap the diagonal entries, negate the off-diagonal ones | [6 −7; −2 4] |
| Divide by the determinant | A⁻¹ = (1/10)[6 −7; −2 4] | [0.6 −0.7; −0.2 0.4] |
| Check | A × A⁻¹: first row 4(0.6) + 7(−0.2) = 1 and 4(−0.7) + 7(0.4) = 0 | The identity matrix |
Worked example: eigenvalues and eigenvectors
Find the eigenvalues and eigenvectors of A = [2 1; 1 2].
| Step | Working | Result |
|---|---|---|
| Characteristic equation | det(A − λI) = (2 − λ)² − 1 = 0 | λ² − 4λ + 3 = 0 |
| Eigenvalues | (λ − 3)(λ − 1) = 0 | λ = 3 and λ = 1 |
| Eigenvector for λ = 3 | (A − 3I)v = 0 gives −x + y = 0 | v = (1, 1) |
| Eigenvector for λ = 1 | (A − I)v = 0 gives x + y = 0 | v = (1, −1) |
| Check | A(1, 1) = (3, 3) = 3(1, 1) | Correct |
Because A is symmetric, its eigenvectors are orthogonal, and A can be diagonalised by an orthogonal matrix.

Linear algebra for engineering, data science and economics
Linear algebra is a tool in many degrees. Tutors link each method to your field: circuits and structures in engineering, principal component analysis and regression in data science, and input–output models in economics.
Related: Mathematics, Abstract Algebra, Calculus 1 to 4 and Linear Algebra (Engineering Level).
Country notes: studying linear algebra outside the UK?
Linear algebra is taught to similar core ideas worldwide, but grading, referencing and course structure differ. FLN tutors work from your own syllabus and handbook and schedule lessons in your time zone. Always follow your module handbook for referencing.
| Country | Where linear algebra is studied | Grading | Referencing usually used |
|---|---|---|---|
| United Kingdom | GCSE and A-Level Further Maths, first-year university linear algebra | GCSE 9–1, A-level A*–E; degrees First, 2:1, 2:2, Third | Few citations; Harvard or numbered if required |
| United States | College linear algebra and matrix theory courses | Letter grades A–F and a 4.0 GPA scale | Few citations; APA or numbered if required |
| Australia | First- and second-year university maths units | HD, D, C, P at university; ATAR for school leavers | Harvard if required |
| Canada | University linear algebra courses | Letter grades or percentages; GPA scales vary by province and university | APA or numbered if required |
| India | CBSE and ISC Class 12, BSc and BTech maths, CSIR NET and GATE | Board exam percentages; university CGPA, often on a 10-point scale | Few citations; as your university specifies |
Students in Ireland, the Gulf, Europe, Africa and Asia can book the same help, with lessons in their own time zone.
How much does linear algebra help cost?
The price of linear algebra help depends on the level, the number of problems or proofs and your deadline. A set of row-reduction questions costs less than a proof sheet on vector spaces. You always see the price first: a fixed quote for homework and assignment guidance, or the tutor's hourly rate for live lessons, with no contract and no minimum number of sessions. Refunds follow our refund policy.

Linear Algebra tutoring: frequently asked questions
Can I get an online linear algebra tutor?
Yes. FLN Tutors matches you with a linear algebra tutor who works one to one over video with a shared whiteboard, using your own course materials.
What is Gaussian elimination?
Gaussian elimination solves a system of linear equations by using row operations to reach row echelon form, then back-substituting to find each variable.
How do I know if a system has no solution or infinitely many?
Row-reduce the augmented matrix. A row of zeros equal to a non-zero number means no solution; free variables mean infinitely many; otherwise there is exactly one.
What is the rank of a matrix?
The rank is the number of linearly independent rows (or columns), which equals the number of pivots in row echelon form.
How do I find the inverse of a matrix?
For a 2 × 2 matrix, swap the diagonal, negate the off-diagonal entries and divide by the determinant. For larger matrices, row-reduce [A | I] to [I | A⁻¹].
What does a zero determinant mean?
A zero determinant means the matrix is not invertible: its columns are linearly dependent and the system Ax = b does not have a unique solution.
What are eigenvalues and eigenvectors?
An eigenvector of A is a non-zero vector v with Av = λv; the scalar λ is its eigenvalue. They show the directions a transformation only stretches.
When is a matrix diagonalisable?
An n × n matrix is diagonalisable when it has n linearly independent eigenvectors. Real symmetric matrices are always diagonalisable.
What is a basis of a vector space?
A basis is a set of linearly independent vectors that spans the space. Every vector can be written uniquely as a combination of basis vectors.
What is the rank–nullity theorem?
For a linear map from an n-dimensional space, rank + nullity = n: the dimension of the image plus the dimension of the kernel equals the dimension of the domain.
How do I prove vectors are linearly independent?
Set a linear combination equal to zero and show the only solution is all coefficients equal to zero.
What is the Gram–Schmidt process?
Gram–Schmidt turns a set of independent vectors into an orthogonal (or orthonormal) set spanning the same space, by subtracting projections one vector at a time.
What is singular value decomposition?
SVD writes any matrix as UΣVᵀ, with orthogonal U and V and non-negative singular values in Σ. It is used in data compression and principal component analysis.
How is linear algebra used in machine learning?
Data are stored as vectors and matrices, models such as linear regression are solved with matrix methods, and techniques such as PCA rely on eigenvectors and SVD.
Do you help with A-Level Further Maths matrices?
Yes. Tutors cover matrix operations, determinants, inverses, transformations and invariant lines for all main exam boards.
Do you help with linear algebra proofs?
Yes. Tutors help you understand definitions, plan proofs and give feedback on your own attempts.
Is linear algebra harder than calculus?
Many students find early linear algebra more mechanical but later topics more abstract. It becomes easier with geometric intuition and steady practice.
Can I get linear algebra homework help the same day?
Often, yes. Short problem sets can usually be explained the same day, depending on tutor availability.
Is it allowed to get linear algebra help?
Yes. Tutoring, worked examples and feedback are a normal part of learning. You should use the explanations to understand the method and submit your own work in line with your school's or university's academic integrity rules. See our academic integrity policy.
Is my linear algebra work kept confidential?
Yes. Your files and details are used only to help you and are not shared with your school or university. See our privacy policy.
