1.4 Rounding Off Numbers
 
   
How to round numbers:  
   
Step 1   Look at the digit to the right of the rounded place value.
     
Step 2  

If the digit is smaller than \(5\), retain the rounded digit.

   

If the digit is greater or equal to \(5\), add \(1\) to the rounded digit.

     
Step 3  

Change all the digits on the right of the rounded place value to \(0\).

     
 
   
EXAMPLE:  
Round 184 524 to the nearest ten thousand.  
\(1\underline{8}4\ 524 \rightarrow 18\color{red}{0\,000}\)
