Math Question: What is the sum of the first ten positive integers multiplied by their respective place value in the number 2020?

To find the sum, we add the products of each positive integer (1 through 10) with its corresponding place value in 2020. Adding (1*2) + (2*0) + (3*2) + (4*0) + (5*2) + (6*0) + (7*2) + (8*0) + (9*2) + (10*0) results in the sum of 28. Therefore, the answer is 28. The sum gives us the combined contribution of the place values (2) in 2020, multiplied by the first ten positive integers, considering the alternate 0 values.

Math Question: What is the sum of all the even numbers between 0 and 2020?

To find the sum of all even numbers between 0 and 2020, we can use the formula for the sum of an arithmetic series. The first even number is 2, and the last even number is 2020. The common difference is 2 since we are adding 2 each time. The formula to find the sum of an arithmetic series is given by S = (n/2)(first term + last term). By substituting the values, we get S = (1010)(2 + 2020) = 1010(2022) = 2,044,220. Therefore, the sum of all even numbers between 0 and 2020 is 2,044,220.

Question: What is the largest prime factor of the number 2020?

To find the largest prime factor of 2020, we start by determining if it is divisible by 2. Since 2020 is an even number, it is divisible by 2. Dividing 2020 by 2 results in 1010. Next, we check if 1010 is divisible by 2, and indeed it is. Dividing 1010 by 2 gives us 505. Again, we repeat the process and divide 505 by 5, obtaining 101. Now, we check if 101 is divisible by any prime numbers up to its square root (√101 ≈ 10.05). We discover that it is not divisible by 2, 3, 5, or 7. Thus, the largest prime factor of 2020 is determined to be 101, as it cannot be divided by any other prime numbers.
