No, it is not true.
Adding and subtracting with decimals primarily involves aligning the decimal points and performing the operation, ensuring that the digits are correctly placed in relation to the decimal. In contrast, multiplying with decimals requires multiplying the numbers as if they were whole numbers, then counting the total number of decimal places in both factors to place the decimal point in the product accurately. While addition and subtraction focus on the positional value of the digits, multiplication also incorporates the overall scale of the numbers involved.
Lets say that u r doing the problem. 5.2 x 2.1 there are altogether 2 numbers to the right of the decimal, so you take out the decimals, multiply, and add the decimal 2 numbers to the left.
When multiplying decimals, you simply multiply the numbers as if they were whole numbers and then count the total number of decimal places in the original numbers. In this case, 0.5 multiplied by 0.5 equals 0.25, as you multiply 5 by 5 to get 25 and then place the decimal point two places from the right.
Multiplying decimals is when you take two numbers with decimal points, ignore the decimals, multiply the numbers like normal, and then count the total number of decimal places in both numbers. The final answer will have that many decimal places. It's like regular multiplication, but with a little extra pizzazz.
It depends on what numbers you are multiplying and how many decimals places they each have. It doesn't always haveto move to the right.
You do the multiplication in exactly the same way. The only extra thing is that when multiplying decimals, you need to place the decimal point (or decimal comma - depending on your country) in the correct position. If one number has, for example, 3 digits after the decimal point, and the other 4, you need to place the decimal point in the result (BEFORE eliminating unnecessary zeros) in such a way that there are, in this example, 7 digits (3 + 4) to the right of the decimal point.
The answer depends on the decimal numbers: there is no simple answer if one (or both) of the decimals is a non-terminating number.
It is the multiplication of numbers where one or more of the multiplicands is in decimal form.

It's because decimals are really fractions and all numbers get smaller when you multiply them by fractions.
Fractions and decimals are usually rational numbers. Besides, multiplying rational and irrational numbers is also similar.
When multiplying decimals, you simply multiply the numbers as if they were whole numbers and then count the total number of decimal places in the original numbers. In this case, 0.5 multiplied by 0.5 equals 0.25, as you multiply 5 by 5 to get 25 and then place the decimal point two places from the right.
The fundamental operations on whole numbers and decimals are addition, subtraction, division, and multiplication. However, multiplying and dividing decimals is a bit more complicated because you have to count decimal points to get an accurate answer.
If two decimal numbers have x and y digits after the decimal point respectively, then their product has (x + y) digits after the decimal point.

That is not necessarily the case.2.5*4.3 = 10.75 which is larger than either of the numbers being multiplied.
