Quick guide
How to use this calculator
- Give A and B matching dimensions.
- Enter every matrix value.
- Read and copy the exact sum.
Calculation method
Add corresponding entries
If A and B have the same number of rows and columns, the entry in row i and column j of A + B is aᵢⱼ + bᵢⱼ.
Worked example
Add two 2 × 2 matrices
Add each entry of [[1,2],[3,4]] to the entry in the same position of [[5,6],[7,8]].
[[1,2],[3,4]] + [[5,6],[7,8]] = [[6,8],[10,12]]
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.
