multiply the numbers like they are integer, then place the decimal dot at a number of digits equal with the sum of decimals of each number you multiplied 10.1 * 10.23 = 103.323 101 * 1023 = 103323
Generally speaking, with the exception of trailing zeroes, the number of decimal places in the answer of a multiplication sum is equal to the sum of the number of decimal places in the question. Therefore, 4.97 x 3.456 contains five decimal places in total, therefore the answer contains five decimal places. In this instance, 4.97 x 3.456 = 17.17632.
.5+.5=1 .5*4=2 2+(.5)= 2.5
Yes. One such example 0.12 + 0.38 = 0.5

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.
When the fractional parts, if any, of the two decimal numbers sum to 1.

to add decimals: -line up the decimal points -then starting at the farthest place to the right, add the decimal in each place -if the sum of the digits in a place are greater than nine,regroup the number to the place to its left. -check the sum by writing each decimal as an equivalent fraction and then adding these numbers or mixed numbers.
The answer depends on how many decimal places are in the summands.
It depends on your level of numerical skill. You can convert the decimal to an approximate fraction and estimate the sum of the two fractions, or you can convert the fraction to an approximate decimal and estimate the sum of the two decimals or, if you are more able you just estimate their sum directly.
To find the number of decimal places in a product of decimal numbers, add up the total number of decimal places in each of the factors. For example, if you have 2.5 multiplied by 4.75, there are two decimal places in 2.5 and two decimal places in 4.75, so the product will have a total of four decimal places.
Pi to 144 decimal places is written thus: 3.14159265358979323846264338327950288419716939937510 58209749445923078164062862089986280348253421170679 82148086513282306647093844609550582231725359 The sum of these first 144 decimal digits (after the decimal point) is 666.
