Common Method of Rounding (Round Up)

Rounding a number means the process of making a number simpler such that its value remains close to what it was. The most common method is to round up. The steps to do so are:

1. Identify the rounding digit. This is the digit in the place value you are rounding to.

2. Examine the next lower place value. This is the digit to the right. 

3. Apply the rules. If the digit to the right is less than 5, keep the rounding digit the same, and convert all digits to the right into zeros. If the digit to the right is 5 or greater, increase the rounding digit by one, and turn all digits to the right into zeros.
