Well, when you're multiplying, you don't always have to move the decimal. It depends on the numbers you're working with. If you're multiplying by a whole number, you can keep the decimal in the same place. But if you're multiplying by a decimal, you may need to move the decimal to the right in the answer. Just remember to take your time and enjoy the process of learning new things!
Multiplying a real number by a positive power of ten moves the decimal point that number (the exponent) of places to the right. Multiplying by a negative power of ten moves it to the left. For example, the -3 power of 10 is 1/1000; multiplying by that moves the decimal point 3 places to the left.
When you move a decimal point to the right you are multiplying a number by 10. For example, take 3.4. If you move the decimal point to the right you get 34. This is the same as: 3.4x10 = 34. Reversing this, you are dividing by 10 by moving the decimal point to the left. For example, take 73. If you move the decimal point to the right you get 7.3. This is the same as: 73/10 = 7.3. If you move a decimal point 2 spaces to the right, you are multiplying by 100, or more generally if you move the decimal point n spaces to the right, you are multiplying by 10^n.

STEP 1:Take out the points and multiply as normal. STEP 2:After multiplying,count the numbers that are after the decimal points. STEP 3:Then look at your answer and put in your decimal places from the right to the left.

It you are multiplying by a number greater than one (or, equivalently, dividing by a number less than one) then the decimal would either stay put or move to the right.
This is because we count in tens so that the place value of a digit is ten times the place value of the digit to its right.

0.10 = 1/10 so that multiplying by 0.10 is the same as dividing by 10.
Yes, by a number between 0 and 1.

Well, honey, you move the decimal to the right when you're multiplying by powers of 10. It's as simple as that. Just count how many zeros are in the power of 10 and shift that decimal over to the right that many places. Easy peasy lemon squeezy!
No. It is the other way round.
