Rounding to the Nearest Ten

Sometimes, you don't need a precise number. You just need a close estimate that's an easy number to work with. This is where rounding comes in. Rounding takes a number and finds the closest "round number" (usually a multiple of 10 or 100).
To round to the nearest 10 means to find the closest multiple of 10 to a given number. Find this by looking at the ones place of the number. If the digit in the ones place is 5 or greater, round up to the next largest multiple of 10. If it is 4 or less, round down to the next lowest multiple of 10.
