Math question: Find the sum of all the digits in the number 1974.

To find the sum of the digits in the number 1974, we break down the number into its individual digits: 1, 9, 7, and 4. Then, we add these digits together: 1 + 9 + 7 + 4 = 21. Hence, the sum of the digits in the number 1974 is 21. To elaborate further, we can see that 1 + 9 + 7 + 4 = 21 because we add the individual values of each digit in the number. The digit 1 contributes 1 to the sum, the digit 9 contributes 9, the digit 7 contributes 7, and the digit 4 contributes 4. When we combine all these contributions, we get a total sum of 21.

Math Question: What is the sum of the digits in the number 1974?

To find the sum of the digits in the number 1974, we can break it down into its individual digits: 1, 9, 7, and 4. Adding these together, we get 1 + 9 + 7 + 4 = 21. Therefore, the sum of the digits in the number 1974 is 21. The sum of the digits in a number helps us understand its properties and relationships with other numbers. In the case of 1974, the sum 21 has interesting mathematical properties. For instance, the sum of the digits gives us the remainder when divided by 9. In this case, 21 % 9 = 3, indicating that 1974 is congruent to 3 (mod 9). Additionally, we can explore the relationship between the sum of digits and divisibility. If the sum of digits is divisible by 3, then the entire number is divisible by 3. In our case, 21 is not divisible by 3, so we can conclude that 1974 itself is not divisible by 3. By understanding such properties, we can dive deeper into number theory and explore various patterns and relationships among numbers. The sum of digits in a number may seem simple, but it opens up a world of mathematical exploration and discovery beyond its apparent simplicity.

Math question: What is the sum of all odd positive integers from 1 to 1974?

To find the sum of odd positive integers, we can use the formula for the sum of an arithmetic series. First, let's calculate the number of terms in this sequence. The last term, 1974, is odd, so our sequence contains (1974-1)/2 + 1 = 988 terms. Now, we can calculate the sum using the formula Sn = (n/2)(a + l), where Sn is the sum of n terms, a is the first term, and l is the last term. The first term a = 1 and the last term l = 1974. Substituting these values, we find Sn = (988/2)(1 + 1974) = 494(1975) = 974,350. So, the sum of all odd positive integers from 1 to 1974 is 974,350.
