IN his head, bitchez! Or in longer words: by noting 1+100=101, 2+99=101, ... , 50+51=101 50 pairs of numbers summing to 101, so 50x101 = 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.
The only numbers that divide evenly into 101 are 101 and 1. This means that 101 is a prime number.
A centillion = 10303 So sqrt(centillion) = (10303)1/2 = 101/2*(10302)1/2 = sqrt(10)*10151 = 3.162*10151 approx.
0.37 is closer to 0.
