Scientific Calculators are one of the basic instruments needed for an Engineer in his career.In most of the colleges the scientific calculator prescribed will be CASIO fx-991 MS.So in this article I have written the usage of scientific calculator for the purpose of matrix multiplication.
Eventhough the usage of scientific calculator is given in the user manual this article may give you some visualisation of the application that it has on Engineering Mathematics-I.
Consider the 3x3 matrix:
|1 3 5|
|3 7 9|
|4 6 2|
