Why is it not necessary to line up the decimal point when multiplying two numbers?
Because the number of digits after the decimal place in a product does not require that.
How do you know where to put the decimal when multiplying decimals?
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.
Must the product of 2 decimals be a decimal?
No. A decimal is a representation of a number such that the place value of any digit is ten times the place value of the digit to its right. It does not require a decimal point. So the decimal numbers, 3 and 4, can be multiplied together to give 1100 in binary.
How do you align decimals when multiplying?
You do not need to align decimal points when multipylng. You multiply the two numbers ignoring the decimal point but ensuring that any trailins 0s are present. The number of digits after the decimal point in the answer is the sum of the number of digits after the decimal points in the two multiplicands.
Why do numbers get smaller when multiplied by a decimal?
It's because decimals are really fractions and all numbers get smaller when you multiply them by fractions.
Is it true when multiplying decimal numbers you must line up the decimals in the two numbers being multiplied?
No, it is not true.
What is the last step for multiplying decimal numbers?
To multiply decimal numbers, the decimal point is ignored and the multiplication is done as though they were (large) integers. The last step is to put the decimal point into the answer by ensuring the same number of digits follow it as were following the decimal points in the numbers multiplied together; trailing zeros can be removed at this point.
What is the term given to the answers when two numbers are multiplied together?
The result of multiplying two numbers is called the product.
Multiplying negative numbers?
any two negative numbers multiplied together equals a positive number. any two positives numbers multiplied together equal positive numbers and any negative and positive numbers multiplied together equals a negative.negative, negative = positivenegative, positive = negativepositive, positive = positive

Why does multiplying numbers by ten move the decimal point to the right?
why does multiplying numbers by ten move the decimal point to the right
How is multiplying a decimal by a whole number the same as multiplying 2 whole numbers?
It is not. When multiplying two whole numbers you need not be concerned about placing the decimal point in the answer.
What is the difference between multiplying decimals and multiplying whole numbers?
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.
Why can you multiply two decimal numbers together and get an answer less than either one of the numbers you multiplied?
For the same reason that you can multiply two proper fractions and get a smaller number than either of them. You are multiplying either decimal by a number that is smaller than 1. As a result you get an answer that is smaller than 1 times the first number.
What is a number multiplied by another number to find a product is called?
This would be called a "factor". A number may be made by multiplying two or more other numbers together. The numbers that are multiplied together are called factors of the final number.
Why does multiplying numbers by 10 move the decimal to the right but multiplying numbers By .10 you move the decimal to the left?
0.10 = 1/10 so that multiplying by 0.10 is the same as dividing by 10.
What is the product of 3.8 and 100?
Product means numbers multiplied together. Multiplying by 10, 100, 1000 etc is easy, you just move the decimal point one place to the right for every zero. To find this product, move the decimal to the right 2 places in 3.8 and we have 380
