Math question: What is the product of 7 and 2 plus the quotient of 21 divided by 3, multiplied by the difference between 8 and 5, squared, minus the square root of 49?

The expression can be written as 7 * 2 + 21 / 3 * (8 - 5)^2 - √49. Simplifying, we have 14 + 7 * (3)^2 - √49. Following order of operations, we get 14 + 7 * 9 - 7. Multiply first, then subtract the square root, resulting in 14 + 63 - 7. Combining terms yields 77 - 7, which equals 70. Hence, the answer is 70.

Question: What is the sum of all odd numbers less than or equal to 14?

To find the sum of all odd numbers less than or equal to 14, we start by listing the odd numbers: 1, 3, 5, 7, 9, 11, 13. Adding them up, we get 1 + 3 + 5 + 7 + 9 + 11 + 13 = 49. Thus, the sum of all odd numbers less than or equal to 14 is 49. These odd numbers represent half of the integers in the range from 1 to 14 (inclusive) since every second number is odd. Therefore, multiplying the sum by 2 gives us 98, which is the sum of all numbers from 1 to 14.

Question: What is the sum of all odd numbers from 1 to 14?

To find the sum of the odd numbers from 1 to 14, we can use the arithmetic series formula. In this case, the first term is 1, the last term is 14, and the common difference between terms is 2 since we are considering odd numbers. The formula for the sum of an arithmetic series is: Sn = (n/2) * (a + l), where Sn is the sum, n is the number of terms, a is the first term, and l is the last term. Plugging in the values, we get: Sn = (7/2) * (1 + 14) = (7/2) * 15 = 52.5. Therefore, the sum of all odd numbers from 1 to 14 is 52.5.
