Example of Matrix Multiplication
Let’s understand how this tool works with a simple example:
Matrix A (2×2):
[ 1 2 ]
[ 3 4 ]
Matrix B (2×2):
[ 5 6 ]
[ 7 8 ]
Calculation:
Multiply rows of Matrix A by columns of Matrix B:
- First Row × First Column: (1×5) + (2×7) = 5 + 14 = 19
- First Row × Second Column: (1×6) + (2×8) = 6 + 16 = 22
- Second Row × First Column: (3×5) + (4×7) = 15 + 28 = 43
- Second Row × Second Column: (3×6) + (4×8) = 18 + 32 = 50
Result Matrix:
[ 19 22 ]
[ 43 50 ]
The calculator performs this entire process instantly for you.
