$[\begin{array}{c} 2.4 - 1 \end{array}] + 2$

Step 1

Subtract $1$ from $2.4$ .

$[\begin{array}{c} 1.4 \end{array}] + 2$

Step 2

Adding $2$ to a $1 \times 1$ square matrix is the same as adding $2$ times the $1 \times 1$ identity matrix.

$[\begin{array}{c} 1.4 \end{array}] + 2 [\begin{array}{c} 1 \end{array}]$

Step 3

Multiply $2$ by each element of the matrix.

$[\begin{array}{c} 1.4 \end{array}] + [\begin{array}{c} 2 \cdot 1 \end{array}]$

Step 4

Multiply $2$ by $1$ .

$[\begin{array}{c} 1.4 \end{array}] + [\begin{array}{c} 2 \end{array}]$

Step 5

Add the corresponding elements.

$[\begin{array}{c} 1.4 + 2 \end{array}]$

Step 6

Add $1.4$ and $2$ .

$[\begin{array}{c} 3.4 \end{array}]$
