its 14 because you always round up when there a five because there is 5 numbers already when you round down (0,1,2,3,4)<5 #'s
the(5,6,7,8,9)<5#'s so then both sides is equal!

if your were rounding $13.50 to the nearest dollar, it would be $14.00 because if it were $13.00, you would be subtracting the 50 cents you owe. If you're thinking in actual numbers, and not dollars, if it's more than .5 (like 5. 52 or 9. 75) then you would round it up to the nearest number. so it would be 5.5 or 9.8. If you want a whole number it would be 6 or 10.

14. 1-4 is rounded down while 5-9 is rounded up.

It would be 14 because anything 5 and over is rounded up.

14
0-4=13
5=9=14

It's rounded to 14. If it's 5 and up then you round it up if it is less than 5 then you round down.

In elementary school they teach you to round up when it's exactly halfway in between. This works fine for most problems that involve rounding, but it was chosen arbitrarily to make things easier, and doesn't always work.
In more advanced math and science problems, especially things using statistical analysis on lots of data, any data points that are exactly on the borderline of the rounding criteria (like your example) are rounded up half the time and down half the time. Exactly how and when this is done so it doesn't introduce errors is sometimes tricky to figure out.
For a brief example, suppose there are ten kids who each eat exactly .5 candy bars. I tell you to ask each kid how much candy they ate, round to the nearest number of bars, and then give me the average. You would round every kid to 1 bar, and then tell me they ate an average of exactly 1 bar each. This answer is off by 100% from the real value of .5 bars each! So rounding this way can introduce serious errors. It's an example of why people say "statistics lie." If you're not doing things correctly, it's easy to use procedures that make statistics that are horribly misleading, sometimes deliberately so.
Anyway, if you're just doing a math problem for school then your teacher probably wants you to just round up when it's half way in between, but remember that this isn't always the right way to go for more advanced problems.

14 cause you round .5 and over up!

If you are talking dollars and cents, anything at $.00 through $.49 is to simpy drop the cents while anything $.50 through %.99 is to drop the cents and add a dollar. Therefore, round up for anything $.50 and above
