To round to the nearest \(10,\) the ones digit and any following digits must be \(0.\) If the original number has a \(0,1,2,3,\) or \(4\) in the ones place, round down to \(0.\) If the original number has a \(5,6,7,8,\) or \(9\) in the ones place, round up to the next multiple of \(10.\)

Rounding is a way to represent one number by another nearby number. For example, suppose you collect peanuts in a basket and count as you go. There are \(362\) peanuts in your basket. Your friend asks how many peanuts you got and you say \(360\). This answer is okay because it is close enough to the actual number.

Example: Here is how you would round the numbers from \(20\) to \(29.\)
