Question 1 · 1 mark · Difficulty 1/3

A matrix P has 2 rows and 3 columns. What is the order of matrix P?

  1. 3 × 2
  2. 2 × 3
  3. 6 × 1
  4. 1 × 6
Show answer & explanation
✓ Answer: B2 × 3
Award 1 mark for correctly stating the order as rows × columns. A is incorrect — this reverses the convention (rows come first, then columns). C and D are incorrect — these represent the total number of elements arranged differently, not the matrix order.
Question 2 · 1 mark · Difficulty 1/3

A farmer in Trinidad records the number of bags of cocoa beans harvested from two estates over three months using matrix M = \begin{pmatrix} 45 & 52 \\ 38 & 41 \\ 50 & 47 \end{pmatrix}. Which type of matrix is M?

  1. Square matrix
  2. Row matrix
  3. Column matrix
  4. Rectangular matrix
Show answer & explanation
✓ Answer: DRectangular matrix
Award 1 mark for identifying that M has unequal numbers of rows (3) and columns (2). A is incorrect — a square matrix has equal rows and columns. B is incorrect — a row matrix has only one row. C is incorrect — a column matrix has only one column.

CXC CSEC Mathematics: Matrices – notation, types, addition, subtraction, multiplication, determinant and inverse of 2×2 matrices FAQ

How many CXC CSEC Mathematics questions on Matrices – notation, types, addition, subtraction, multiplication, determinant and inverse of 2×2 matrices are there on Kramizo?
Kramizo currently has 21 exam-board-aligned practice questions on Matrices – notation, types, addition, subtraction, multiplication, determinant and inverse of 2×2 matrices for CXC CSEC Mathematics, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real CXC paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for CXC CSEC students preparing for Mathematics?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Matrices – notation, types, addition, subtraction, multiplication, determinant and inverse of 2×2 matrices practice with other Mathematics topics or even switch to a totally different CXC subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Matrices – notation, types, addition, subtraction, multiplication, determinant and inverse of 2×2 matrices questions aligned to the official CXC CSEC Mathematics syllabus?
Every question is written against the published CXC CSEC Mathematics specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CXC paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from CXC.
How is Matrices – notation, types, addition, subtraction, multiplication, determinant and inverse of 2×2 matrices typically tested on CXC CSEC Mathematics papers?
Matrices – notation, types, addition, subtraction, multiplication, determinant and inverse of 2×2 matrices appears across multiple question types on real CXC CSEC Mathematics papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
