Round the number to the nearest thousands.

Example:

Step1: Underline the number in the 'thousands' place value.

Step 2: Identify the number for 'hundreds'.

Digits in the 'thousands' place value  Digits in the 'thousands' place value

add 0                                                   add 1

\(\begin{aligned} &\color{red}{7}\;3\;2\;6\quad\Longrightarrow\quad\;\color{red}{7}\;3\;2\;6 \\&\small{+0} \end{aligned}\)     

Step 3: Change the number in the 'hundreds', 'tens' and 'ones' place value to zero.

\(7\;\color{red}{3}\;\color{red}{2}\;\color{red}{6}\quad\Longrightarrow\quad7\;\color{red}{0}\;\color{red}{0}\;\color{red}{0}\)

So, 7326 rounded to the nearest thousands is 7000.
