<span>In the laws of mathematics, especially in rounding off digits, you
should take note of the digit following that number no matter how long or short
a number is. If the numberis preceded by numbers between 0-4, the number does
not change. However if its is preceded by numbers between 5-9, add one to the
number. For example, 145698. If it is rounded off to the nearest hundreds,
since 9 is the number after 6, add 1 to 6 and it becomes 145700. If it is
rounded off to the nearest hundred thousands, since 4 is the number after 1,
you do not add, the number stays the same and it becomes 100000</span>
