Rounding numbers

提高自己的技能，在舍入数字。

In maths, you can round up or round down. When you round up a number, the result is half or greater than the one you are rounding. Let's say you want to round to the nearest tenth. If you were given the value 26, you would round up because 6 is greater than half of ten (5). Rounding down occurs when the value is less than half. This app provides students, parents, and teachers with several tests about rounding skills. Endless series of exercises to practice with.
