Quick guide

How to use this calculator

  1. Give A and B matching dimensions.
  2. Enter every matrix value.
  3. Read A − B in the original row and column order.

Calculation method

Subtract corresponding entries

For equally sized matrices, subtract each entry of B from the entry occupying the same position in A.

Worked example

Subtract two 2 × 2 matrices

Subtract [[1,2],[3,4]] from [[5,6],[7,8]].

[[5,6],[7,8]] − [[1,2],[3,4]] = [[4,4],[4,4]]

Supported inputs

Precision and limits

Matrix size

Each input matrix may contain 1–6 rows and 1–6 columns.

Entry precision

Each signed decimal may contain up to 30 digits and 15 decimal places.

Exactness

Finite decimals are converted to reduced fractions before calculation; matrix arithmetic is not rounded.
