For every two matrices $\mathbf{A}=[a_{ij}], \mathbf{B} = [b_{ij}] \in \mathbb{R}^{m \times n}$ is valid: $$\mathbf{A} + \mathbf{B} = \mathbf{B} + \mathbf{A},$$. 12 & -12 & -16 & 10 \\ -31 & 9 & 4 & -57 \end{bmatrix}=, \begin{bmatrix} 1 + 0 & 2 +(-3) & -4 +16 & 3 + (-98) \\ -9 +12 & 11 + (-12) & 36 + (-16) & -6 +10 \\ 41 + (-31) & -3 +9 & 17 +4 & 76 + (-57) \end{bmatrix} =. Multiply all of the numbers in the second row of Matrix M by the “matching members” in the first column of Matrix N. Then sum these products to get the lower-left number in the new matrix. This means that element $c_{ij}$ is the scalar product of elements that are located in $i$-th row of matrix $\mathbf{A}$ and in $j$-th column of matrix $\mathbf{B}$. Once they have determined the answers to all the questions, learners will cut out the correct answer cards and paste them in the appropriate places on their paper (scissors and glue … The result of addition of these two matrices is matrix $\mathbf{C}=[c_{ij}]$ which has the same dimensions and, $$a_{ij} + b_{ij} =c_{ij}, \forall i= 1, \ldots , m , \forall j = 1, \ldots , n$$, $\begin{bmatrix} a_{11} & a_{12} & a_{13} & \ldots & a_{1n} \\ a_{21} & a_{22} & a_{23} & \ldots & a_{2n} \\ a_{31} & a_{32} & a_{33} & \ldots & a_{3n} \\ \vdots & \vdots & \vdots & \ddots & \vdots\\ a_{m1} & a_{m2} & a_{m3} & \ldots & a_{mn} \end{bmatrix} + \begin{bmatrix} b_{11} & b_{12} & b_{13} & \ldots & b_{1n} \\ b_{21} & b_{22} & b_{23} & \ldots & b_{2n} \\ b_{31} & b_{32} & b_{33} & \ldots & b_{3n} \\ \vdots & \vdots & \vdots & \ddots & \vdots\\ b_{m1} & b_{m2} & b_{m3} & \ldots & b_{mn} \end{bmatrix} $, $=\begin{bmatrix} a_{11}+b_{11} & a_{12}+b_{12} & a_{13}+ b_{13} & \ldots & a_{12n}+ b_{1n} \\ a_{21} + b_{21} & a_{22} + b_{22} & a_{23} + b_{23} & \ldots & a_{2n}+ b_{2n} \\ a_{31}+b_{31} & a_{32}+ b_{32} & a_{33}+ b_{33} & \ldots & a_{3n}+ b_{3n} \\ \vdots & \vdots & \vdots & \ddots & \vdots\\ a_{m1}+b_{m1} & a_{m2}+b_{m2} & a_{m3}+b_{m3} & \ldots & a_{mn}+b_{mn} \end{bmatrix}=[c_{ij}].$, $$\mathbf{A} = \begin{bmatrix} 1 & 2 & -4 & 3 \\ -9 & 11 & 36 & -6 \\ 41 & -3 & 17 & 76 \end{bmatrix}, $$, $$\mathbf{B} = \begin{bmatrix} 0 & -3 & 16 & -98 \\ 12 & -12 & -16 & 10 \\ -31 & 9 & 4 & -57 \end{bmatrix}.$$, \begin{bmatrix} 1 & 2 & -4 & 3 \\ -9 & 11 & 36 & -6 \\ 41 & -3 & 17 & 76 \end{bmatrix}+ \begin{bmatrix} 0 & -3 & 16 & -98 \\ Students have fun with Scavenger Hunts. $c_{11} = a_{11}b_{11} + a_{12}b_{21} + a_{13}b_{31} + \ldots + a_{1n}b_{n1}$. If $\mathbf{A} = [a_{ij}] \in \mathbb{R}^{m\times n} $ and $\mathbf{B} = [b_{ij}] \in \mathbb{R}^{n\times r} $ , then their product is defined as matrix $\mathbf{A} \mathbf{B} = [c_{ij}] \in \mathbb{R}^{m\times r}$, where $[c_{ij}] = a_{i1} b_{1j} +a_{i2} b_{2j} + a_{i3} b_{3j} + \ldots + a_{in} b_{nj}$. A + B = B + A, that is, the addition of matrices is commutative. This is matrices review RIDDLE worksheet.
