4. Rounding
Steps:
1- Find your place.
2- Look next door (to the right side).
3- 5 or more raise the score of your place.
4- 4 or less keep your number as it is.
5- All numbers on the right side will be zeros.
6- All numbers on the left side will be the same.
Example:
Round number 23,690 to the nearest thousands.
My place 23,690
Next door 23,690 more than 5 so raise the score of my digit.
24,000
Same Numbers on the right side will be zeros.
3,000 will be 4,000
