Oh, dude, like, when you add -3x^2 - 5x + 1 and 8x^2 - 2x - 9, you just gotta combine like terms. So, you end up with 5x^2 - 7x - 8. Easy peasy lemon squeezy.

The sum of adding all the numbers between 1 and 76 (2 through 75) is 2,849. If you include 1 and 76 the result is 2,926.
The result of adding 1, 2, and 3 is 6. When you add numbers, you are combining their values to get a total. In this case, by adding 1, 2, and 3, you are taking the number 1 and adding 2 to it, which gives you 3. Then, you take that result (3) and add 3 more to it, which gives you 6. So , the sum of 1, 2, and 3 is 6. Essentially, you are adding each number one at a time until there are no more numbers to add.

A Fibonacci number is found by starting with 0, then adding 1=1, then add 1= 1+1=2, then add 1+2=3, then add 2+3=4, then add 4+3=7. If we keep it up we end up with 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ... . The Fibonacci numbers are found by starting with 0, adding 1, then adding the result to the integer immediately preceding the equals sign.
