How do you add numbers 1 tru 100?
There are two ways to solve this problem: You may notice that if you take away 100 from the series and add the smallest and largest number (1 + 99), you get 100. Then if add the next numbers in (2 + 98), you also get 100. Soon, you see a pattern. 3 + 97 = 100, 4 + 96 = 100 and so on. If you do this all the way to 50, you get 100, forty-nine time or 49*100 which 4900. You then add the 100 you took away earlier and add that to 4900 to get 5000. Lastly, because there is only one 50 in 1 to 100, it stays as 50 and you add that to 5000 to get the answer: 5050. The second way is to use the summation equation. This only works if you are starting from 1 and adding all the consecutive numbers to a certain number, say n. The equation is n(n+1)/2 where "n" is the final number in the series which in this case is 100. So 100(100+1)/2 = 100(101)/2 = 10100/2 = 5050.
What do you get when you add all the numbers 1-100 up?
-99
What is a quicker way to find the sum of numbers 1 to 100?
If you add the first and the last number, you have a sum of 101. The second number from the left and the second number from the right will also add up to 101. If you continue in this way, you get 50 pairs of numbers, each of which has a sum of 101, so the final result is 50 x 101.
How did guass answer 1 plus 2 plus 3 etc?
The question was: Add up all the numbers up to 100.Der jungen Karl Friedrich didn't guess. He reasoned:100 + 1 = 10199 + 2 = 10198 + 3 = 10197 + 4 = 10196 + 5 = 101In this way, with the 100 numbers I can make 50 pairs, and every pair totals 101.So all 100 numbers add up to (50 times 101) = 5,050They say he was something like 5 years old at the time.
