I'm sorry, but it is not practical to provide the first 20 million digits of pi in just 3-4 sentences. However, I can tell you that pi is an irrational number, meaning it has an infinite number of non-repeating digits. While it is possible to calculate and store a large number of digits of pi using computer algorithms, listing the first 20 million digits here would be beyond the scope of this format.
We will use an example and narrate the steps...12X12 First, set up the multiplication problem in a vertical format...12X12____=24 Second, multiple the second digit of the bottom number (in this case, 2) by both digits of the top number, and write the products from right to left (if it comes out to ten or higher, carry the first digit of the number that is ten or higher over to the first digit of the second number and add that to the product of one of the bottom digits multiplied by one of the top digits)...12X12____=24+120 Next, add a 0 below the number you came out with (24). Then, multiply 1 by 2 to ..........get 2 and add that to the left of the 0, and multiply 1 by 1 to get 1, and add the 1 to the left of the 2. Then, finally add 120 and 24 to get 144. That is your answer._____144

Large numbers can be multiplied on paper using a method called long multiplication. It functions similarly to regular on-paper multiplication, but is a little bit more complex as it involves two numbers with two or more digits. Below are the steps to go through, using an example1. Set out the numbers as shown below.12x11------2. Multiply the first digit of the bottom number by the top number.12x11------123. Underneath this number, place a zero.12x11------1204. Multiply the second digit of the bottom number by the top number, placing your answer after the zero.12x11------121205. Add the products together to obtain your final answer.12x11------12120------132When dealing with numbers with more digits, an additional zero will need to be added. For example, when multiplying by the third digit of the bottom number, two zeros are to be added before the product.
You know when to overestimate when the last number is over five then you round it up. Under is the last number below five you round down.
Impossible. With all multiples of nine the product of its digits is 9. Take, for exampe, 117 or 153.
The answer is below:
41
which number below is a multiple of 9
So there is a rule about multiples of 9 in general: something is a multiple of 9 if and only if its digits add up to a multiple of 9. 6+4 = 10, so it is not a multiple of 9. There's also a neat trick to remembering the multiples of 9 below 99 with your fingers, but you can look this up if you're interested.
No. A multiple of a number cannot be below the number itself. In this case, 48 is below 84 and is not a multiple of it. The LCM of 24 and 84 is 168.
add numbers below to each number at the top
That would be 29.
what number is prime to 40 29 - it's a prime number (divisible only by 1 and itself) and if you sum the two digits 2 + 9 = 11
Numbers below 100 which can be divided equally between 3 and 4 are:12, 24, 36, 48, 60, 72, 84, 96Therefore, the two-digit number whose digits add up to 15 and which shares 3 and 4 as common factors is 96.
-100 all the way to -999
298.
