2×2 matrix determinant calculator (with LaTeX)

given matrix

\[ A = \begin{bmatrix} a & b \\ c & d \end{bmatrix} \]

determinant formula:

\[ \det(A) = ad - bc \]

enter values (fractions like -1/3 or decimals). press calculate.

\(\det \begin{bmatrix} a & b \\ c & d \end{bmatrix}\)

| a b ; c d | = a·d − b·c

\(\text{matrix entries: } \begin{bmatrix} a & b \\ c & d \end{bmatrix}\)

\(a\) (row1,col1)

\(b\) (row1,col2)

\(c\) (row2,col1)

\(d\) (row2,col2)

\(\text{precision}\)

decimal places

\(\det(A) = a d - b c\)

value:

result in decimal format (fractions evaluated).
