Frequently Asked Questions
How do I know where to place the decimal point when multiplying decimals?
Count the total number of decimal places in both numbers you are multiplying. Then, in your answer, count that many places from the right and insert the decimal point.
Can we add extra zeros to the right of a decimal number?
Yes, adding zeros to the very end of a decimal number (after the last non-zero digit) does not change its value, and it helps when lining up decimals for addition or subtraction.
Which direction does the decimal point move during division by 10 or 100?
When dividing by powers of 10, the decimal point moves to the left by as many places as there are zeros.
