Below is a calculator to find the inverse of 2 by 2 matrices. If A is 2 by 2 matrix given by

2 by 2 matrix [[a,b],[c,d]].

then matrix A has an inverse if and only if ad - bc is not equal to zero. When matrix A has an inverse, it is given by

inverse of a 2 by 2 matrix.

How to use the calculator 1 - Enter the coefficients a,b,c and d as real number and press "enter". If by mistake characters other than numbers are entered, the calculator does not display any answer.

For matrices that have no inverses, the answer is "no inverse".
