Question: What is the sum of all the odd numbers from 1 to 1379?

To find the sum, we can apply the arithmetic series formula Sn = n/2(a + L), where Sn represents the sum, n is the number of terms, a is the first term, and L is the last term. To determine the number of terms, we can use the formula (L - a)/2 + 1. Since the first odd number is 1 and the last odd number is 1379, we have the number of terms as (1379 - 1)/2 + 1 = 690. Now, we can calculate the sum by substituting the values into the formula: Sn = 690/2(1 + 1379) = 690/2(1380) = 690/2 * 1380 = 237,690. Hence, the sum of all the odd numbers from 1 to 1379 is 237,690.

Math Question: If 1379 is multiplied by its reverse, what is the resulting product?

To find the product, we need to multiply 1379 by the reverse of itself, which is 9731. Therefore, the product is 13,438,249. By multiplying the corresponding digits, we get (1x9) in the units place, (3x3) in the tens place, (7x7) in the hundreds place, and (9x1) in the thousands place. Finally, when we sum these products, we obtain the answer.

Math Question: What is the sum of the factors of the number 1379?

To find the factors of 1379, we need to determine all the numbers that divide 1379 with no remainder. The factors of 1379 are 1, 7, 197, and 1379 itself. Adding these factors together, we get 1 + 7 + 197 + 1379 = 1584. Therefore, the sum of the factors of 1379 is 1584.
