# Matrix Trace Calculator

The calculator will find the trace of the matrix, with steps shown.

If the calculator did not compute something or you have identified an error, or you have a suggestion/feedback, please write it in the comments below.

Find the trace of $\left[\begin{array}{ccc}-2 & 5 & 7\\4 & 6 & 1\\8 & -9 & 5\end{array}\right]$.
The trace of a matrix is the sum of its diagonal elements, so the trace is $-2 + 6 + 5 = 9$.
The trace of the matrix equals $9$A.
