Basics involve place value counting from the last number, which is the ones place.
Rounding is included - looking to the right of the place being rounded to - if it

is 4 or less the rounded place stayed the same and all numbers flowing are changed to zeroes.

is 5 or more the rounded number goes up followed by zeroes.
