Calculate 8×8 matrix addition, subtraction, multiplication, determinants, inverses, and Ax = b solutions from entered matrix values.

Enter eight rows of eight numbers in each matrix. Separate numbers with spaces or tabs; enter zero explicitly.

One row per line. Spaces or tabs separate entries. Decimals and scientific notation are accepted; no comma grouping.

One row per line, eight entries per row. No blank entries or comma grouping.

8X8 Calculator Formulas

The following formulas are used to perform matrix operations.

Addition: R = A + B Subtraction: R = A - B Multiplication: Rᵢⱼ = sumₖ₌₀⁷ Aᵢₖ cdot Bₖⱼ
  • R is the resulting matrix.
  • A is the first 8×8 matrix.
  • B is the second 8×8 matrix.

Select the operation, then enter each matrix as eight lines of eight numbers separated by spaces or tabs. Enter zeros explicitly. Results use exact fractions for the decimals entered; the matrix result can be scrolled horizontally on narrow screens.

What is an 8X8 Calculator?

Definition:

An 8X8 Calculator is a tool that allows you to perform matrix operations—such as addition, subtraction, and multiplication—on two 8×8 matrices, where each operation is computed according to standard mathematical rules.

How to Use the 8X8 Calculator?

Example Problem:

The following example outlines the steps required to perform matrix addition using the 8X8 Calculator.

First, input the values in Matrix A. In this example, assume every entry in Matrix A is set to 1.

Next, input the values in Matrix B. In this example, assume every entry in Matrix B is set to 2.

Finally, select the Addition operation and click Calculate.

R = A + B

Since 1 + 2 equals 3, every entry in the resulting matrix will be 3.

FAQ

What operations does the 8X8 Calculator support?

The calculator supports addition, subtraction, matrix multiplication, determinant and inverse, and solving A x = b. Singular matrices have no inverse; inconsistent and nonunique systems are reported explicitly.

Can I use this calculator for matrices of different sizes?

This calculator is specifically designed for 8×8 matrices. For other sizes, please use a calculator built for those dimensions.

How is the multiplication operation performed?

In multiplication, each element of the resulting matrix is calculated as the sum of the products of corresponding elements from the rows of Matrix A and the columns of Matrix B.
