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.

There is no mathematical difference.
Without decimals there would be no difference between dollars and cents.
That is called the difference between them.
the incerase is adding and the decrease is subtracting :)

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.
That is called the difference between them.

"Delta" is often used to mean "the difference" between two numbers, and that is the same as subtracting. When you subtract, the answer is called the "difference."
The difference between 5.06 and 3.2 is calculated by subtracting 3.2 from 5.06. This results in 1.86. Therefore, the difference is 1.86.
