Answer 1

Let's begin by listing out the information given to us:

$11,312$

Expanded notation implies that we will breakdown the number into its simple form and to show the value of each digit

$\begin{gathered} 11,312\Rightarrow1\cdot10,000+1\cdot1,000+3\cdot100+1\cdot10+2\cdot10 \\ \Rightarrow10,000+1,000+300+10+2 \end{gathered}$
