5050. It is essentially 101 x 50, an interesting mathematical property, first stated by Carl Friedrich Gauss.
101 x 50 equals 5,050
Actually he did not invent arithmetic progression, but he had this insight as a 7 years old young student. When his teacher asked the class to sum all numbers from 1 to 100, the young Gauss did not need more than a few seconds to write "5050" in his slate. he noticed that 1+100=101, 2+99=101, 3+98=101, ... formed a sequence of 50 pairs that could summarize the calculation to 50x101= 5050. Gauss is today considered by many as the greatest mathematician that ever lived.
the answer to 1+2+3... all the way to 100 in less then a minute (1+99)+(2+98)+(3+97)+...+(49+51)=4900+100+50=5050
The sum of the first 100 numbers is 5050. There is a formula to do this, which was discovered by Carl F Gauss. S = ( N * ( N +1 ) ) / 2 so in this case: S = (100 * 101) / 2 S = 10100 / 2 S = 5050

5050. It is essentially 101 x 50, an interesting mathematical property, first stated by Carl Friedrich Gauss.
101 x 50 equals 5,050
You see, 1+100= 101 and 2+99= 101 also. So, 3+98 must equal 101. Hence, that pattern repeats 50 times so 50×101=5050. So the answer is 5050. Carl Friedrich Gauss realized this.

I think you're referring to Carl Friedrich Gauss (1777-1855). The story is that his primary school teacher asked his pupils to add the integers from 1 to 100 believing that this would occupy them for some time. Gauss quickly gave the correct answer of 5050 presumably by reordering the terms thus: 1 + 2 + 3 + 4 + 5 + 6 + ... + 100 = (1+100) + (2+99) + (3+98) + (4+97) + (5+96) + ... + (50+51) = 101 x 50 (each of the 50 pairs adds to 101) = 5050. This particular story may not have actually happened but there is no doubt that Gauss was one of the greatest mathematicians in history.
the answer to 1+2+3... all the way to 100 in less then a minute (1+99)+(2+98)+(3+97)+...+(49+51)=4900+100+50=5050
The formula for calculating the Gauss sum from 1 to 100 is n(n1)/2, where n is the number of terms in the sequence.
Gauss was a German mathematician who, as a child prodigy, was able to calculate the sum of all numbers from 1-100 in less then a minute.
The sum of the first 100 numbers is 5050. There is a formula to do this, which was discovered by Carl F Gauss. S = ( N * ( N +1 ) ) / 2 so in this case: S = (100 * 101) / 2 S = 10100 / 2 S = 5050
Gauss's method was to find the sum of 1-100. He tried adding with pairs 1 + 100 = 101, 2 + 99 = 101 and so on. Each pairs was going to equal 101. Half of 100 is 50, 50 x 101 = 5,050.
