Multiply two decimals: where does the decimal point go?

Full solution

Q. Find the product.

\newline

-2 \cdot\left[\begin{array}{cc} -1 & 3 \\ 4 & 2 \end{array}\right]=

Understand Operation: Understand the operation to be performed. $\newline$ We need to multiply each element of the matrix by $-2$ . This is a scalar multiplication of a matrix.
Multiply First Element: Multiply the first element of the matrix by $-2$ . $\newline$ $-2 \times -1 = 2$
Multiply Second Element: Multiply the second element of the first row by $-2$ . $\newline$ $-2 \times 3 = -6$
Multiply First Row: Multiply the first element of the second row by $-2$ . $\newline$ $-2 \times 4 = -8$
Multiply Second Row: Multiply the second element of the second row by $-2$ . $\newline$ $-2 \times 2 = -4$
Write Resulting Matrix: Write down the resulting matrix with the products calculated in the previous steps. $\newline$ The resulting matrix is: $\newline$ $\begin{bmatrix} 2 & -6 \ -8 & -4 \end{bmatrix}$
