Round function

The "round" function is like when you are counting your marbles and your mom says to put them in the jar. But, the jar can only hold a certain amount of marbles. So, you have to take some marbles out and put them in another jar. But, you can't just take one or two marbles out because that wouldn't be fair. You have to take a bigger group of marbles out at once. That's what the "round" function does. It takes a number and decides what the closest number is that can fit into a certain jar. It can round up or down depending on the rules you set. So, if you have 6.7 marbles and the jar can only hold whole marbles, the "round" function would take away the 0.7 marbles and put them in a different jar. The round function is very helpful when you need to make numbers easier to work with, just like putting your marbles in jars can help you keep track of them.
