Carl Friedrich Gauss realized that the sum of the numbers from 1 to 100 could be calculated quickly by pairing the numbers. He noticed that pairing the first and last numbers (1 + 100), the second and second-to-last (2 + 99), and so on, each pair always summed to 101. Since there are 50 such pairs in the range from 1 to 100, he multiplied 101 by 50, resulting in a total of 5,050. This clever method significantly sped up the calculation.
5050. It is essentially 101 x 50, an interesting mathematical property, first stated by Carl Friedrich Gauss.
Carl Friedrich Gauss did not discover triangular numbers, but he is known for his early work with them as a child. At the age of 8, he famously summed the first 100 integers quickly by realizing that they could be paired to form triangles. The concept of triangular numbers, which are the sums of the first ( n ) natural numbers, has been known since ancient times, long before Gauss's contributions in the late 18th century.
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

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.
Carl Friedrich Gauss, often referred to as the "Prince of Mathematicians," made significant contributions to various fields, including number theory, statistics, and astronomy. One interesting event in his life was at age 7 when he quickly solved a problem posed by his teacher to sum the integers from 1 to 100, demonstrating his extraordinary mathematical talent. Another notable moment was his publication of "Disquisitiones Arithmeticae" in 1801, which laid the foundations for modern number theory. Additionally, Gauss made pivotal advancements in the field of astronomy, notably predicting the orbit of the asteroid Ceres shortly after its discovery.
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
