Problem

Find the determinant of [[7, 1], [4, 8]]

Answer

52

Worked solution

(7×8) − (1×4) = 56 − 4 = 52

Notes

  • · Change the problem number to generate a new random problem.
  • · Try to solve it yourself before checking the worked solution.

Determinant Practice Generator — How It Works

Determinant Practice Generator — How It Works

Practicing the same type of problem repeatedly is one of the best ways to build fluency. The Determinant Practice Generator generates a fresh random problem for finding the determinant of a 2×2 matrix, with a worked solution so you can check your work. Try the Determinant Practice Generator — instant results, no sign-up.

How it works

  1. The tool generates a problem based on a “problem number” — change the number to get a new (but reproducible) problem.
  2. Try to solve the problem yourself.
  3. Reveal the answer and worked solution to check your work.

The underlying formula

(a×d) − (b×c)

Tips

  • Work through several problem numbers in a row for repeated practice.
  • If you get a problem wrong, re-read the worked solution step by step before moving to the next one.
  • This tool is a starting point — for harder problems, try larger numbers or combine it with other practice generators in Math & Education.

FAQ

Is this free?
