What are the rules for significant digits when multiplying?
If two numbers have m and n significant digits, respectively, then then product can have at most m+n. However, the normally it is the minimum of m and n.
What does product of digits mean?
Mutilply the values of the digits.
The sum of your digits is 16 The product of your digits is 64 What number are you?

Why is the second partial product greater than the first partial product when you multiply by two 2-digit numbers?
The answer will depend on the order in which you do partial products. It is quite common in the UK for the first partial product to be the two digits in the tens' place and so that is often the largest. This ties in with the method for multiplying two binomials when they move on to algebra.
How do you multiply a mixed decimals?
Multiplying mixed decimals is almost just like multiplying whole numbers.For example:5.21 * 1.1You multiply these two numbers as if they didn't have decimal points, and you get 5,731; however, don't forget that you have decimals!Count the total number of digits after the decimal in each factor. You should get 3 since 5.21 has two digits after the decimal, and 1.1 has one digit after the decimal. 2 + 1 = 3Since you have 3 for that total, take the product (which is 5,731) and move the decimal point of that 3 spaces to the left.Your final product is 5.731:]

How do you know where to put the decimal when multiplying decimals?

What are the rules for significant digits when multiplying?
If two numbers have m and n significant digits, respectively, then then product can have at most m+n. However, the normally it is the minimum of m and n.
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.
When multiplying decimals how do you determine where to place the decimal in the answer?
If the two multiplicands have X and Y digits after the decimal place then their product (before removing any trailing 0s) has (X+Y) digits after the decimal point.
What is the two digit number are added they give a sum that is half as large as the product of multiplying the two digits?
44. Also works for 36, 63.
When multiplying decimals count the decimals digits in each?
Yes.
Why is it important to line up the decimal points when adding or subtracting but not when multiplying?
Because when adding or subtracting, the operations must take account of the place values of individual digits in the numbers. When multiplying, only the overall order of magnitudes are relevant for placing the decimal point in the product.
What does product of digits mean?
Mutilply the values of the digits.
Of example How many digits can the product of two 2 digit numbers have?
It should be obvious (it is, isn't it? am I expecting too much of today's educational system?) that the largest possible result of multiplying two two digit numbers is 99x99 = 9801, which has four digits, and the smallest possible result is 10x10 = 100, which has three digits.
