What can I learn in finding the sum of consecutive numbers?

1 answer:

8 0

Answer:

By using Carl Gauss's clever formula, (n / 2)(first number + last number) = sum, where n is the number of integers, we learned how to add consecutive numbers quickly. We now know that the sum of the pairs in consecutive numbers starting with the first and last numbers is equal.

How do i find the hypotenuse using the pythagorean theorem

Svetach [21]

Step-by-step explanation:

You multiply the two other sides by itself like 12x12=144 and do that for all the sides that you know then you add up all of the numbers you got from adding like 144 plus 64 equals 208 and then 208 is the hypotenuse.
