Rounding  means we are finding the closest  benchmark number. abenchmark number  is one that is easy to  use  in operations and/or quicker to say and write. a  number  line can us  round  by showing the closestbenchmark number. five is the midpoint  between  0 and 10.

In  mathematics, the  pythagorean theorem, also known as  pythagoras' theorem, is a fundamental relation in  euclidean geometryamong the three sides of a  right triangle. it states that the square of the  hypotenuse  (the side opposite the  right angle) is equal to the sum of the squares of the  other two sides. the  theorem  can be written as an  equationrelating the lengths of the sides  a,  b  and  c, often called the "pythagorean equation".
