# Matrix Scalar Multiplication Calculator

The calculator will multiply the given matrix by the given scalar, with steps shown. It handles matrices of any size up to 10x10 (2x2, 3x3, 4x4 etc.).

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 $$3 \left[\begin{array}{cc}4 & 5\\-2 & 0\\1 & 7\end{array}\right]$$$. ## Solution Multiply each entry of the matrix by the scalar: $$\color{SaddleBrown}{\left(3\right)}\cdot \left[\begin{array}{cc}4 & 5\\-2 & 0\\1 & 7\end{array}\right] = \left[\begin{array}{cc}\color{SaddleBrown}{\left(3\right)}\cdot \left(4\right) & \color{SaddleBrown}{\left(3\right)}\cdot \left(5\right)\\\color{SaddleBrown}{\left(3\right)}\cdot \left(-2\right) & \color{SaddleBrown}{\left(3\right)}\cdot \left(0\right)\\\color{SaddleBrown}{\left(3\right)}\cdot \left(1\right) & \color{SaddleBrown}{\left(3\right)}\cdot \left(7\right)\end{array}\right] = \left[\begin{array}{cc}12 & 15\\-6 & 0\\3 & 21\end{array}\right]$$$
$$3 \left[\begin{array}{cc}4 & 5\\-2 & 0\\1 & 7\end{array}\right] = \left[\begin{array}{cc}12 & 15\\-6 & 0\\3 & 21\end{array}\right]$$\$A
