Math Question: What is 63 divided by 3, multiplied by 7, subtracted by 15, added to half of 84, and then divided by 2?

Let's break down the question step by step. 1. 63 divided by 3 equals 21. 2. 21 multiplied by 7 equals 147. 3. 147 subtracted by 15 equals 132. 4. Half of 84 is 42. 5. 132 added to 42 equals 174. 6. Lastly, 174 divided by 2 equals 87. Therefore, the final answer is 87.

Math question: What is the sum of all natural numbers from 1 to 63?

To find the sum of the natural numbers from 1 to 63, we can use the formula for the sum of an arithmetic progression: Sum = (n/2)(first term + last term). Here, the first term is 1, the last term is 63, and there are a total of 63 terms. Plugging these values into the formula, we get Sum = (63/2)(1 + 63) = 31.5 * 64 = 2016. Hence, the sum of all natural numbers from 1 to 63 is 2016. This can be explained by visualizing that when these numbers are added, every number pairs up with another so that each pair sums to 64. And since there are 31 such pairs, the total sum is 31 * 64 = 2016.

Math question: What is the sum of all numbers from 1 to 63?

To find the sum of numbers from 1 to 63, we can use the formula for the sum of an arithmetic series. The formula is: S = (n/2)(a + l) where S is the sum, n is the number of terms, a is the first term, and l is the last term. In this case, n = 63, a = 1, and l = 63. Plugging these values into the formula, we get: S = (63/2)(1 + 63) = 31.5(64) = 2016. Hence, the sum of all numbers from 1 to 63 is 2016.
