    • Decide which is the last digit to keep
    • Leave it the same if the next digit is less than 5 (this is called <i>rounding down</i>)
    • But increase it by 1 if the next digit is 5 or more (this is called <i>rounding up</i>)

    Example: Round 74 to the nearest 10

    • We want to keep the "7" (it is in the 10s position)
    • The next digit is "4" which is less than 5, so no change is needed to "7"

    Answer: 70

    (74 gets "rounded down")

    Example: Round 86 to the nearest 10

    • We want to keep the "8"
    • The next digit is "6" which is 5 or more, so increase the "8" by 1 to "9"

    Answer: 90

    (86 gets "rounded up")
