Two integers whose sum is 0 and product is -64?

Last Answer : answer:The video lost me about 40 seconds in then he made this leap from 1+2+3+4… to 1+ x2 + 2x squared and so on. That may be obvious to a mathematician, but to me it was a giant leap of faith. And logically it doesn’t make sense either. So I am just as confused as you are.

When the celebrated German mathematician Karl Friedrich Gauss (1777-1855) was nine he was asked to add all the integers from 1 through 100. He quickly added 1 to 100, 2 to 99, and so on for 50 pairs of numbers each adding to 101. 50 X 101=5,050.Now find the sum of all the digits in integers from 1 through 1,000,000,000.That's all the digits in all the numbers, not all the numbers themselves. -Riddles

Last Answer : The numbers can be grouped by pairs: 999,999,999 and 0; 999,999,998 and 1' 999,999,997 and 2; and so on.... There are half a billion pairs, and the sum of the digits in each pair is 81. The digits in the unpaired number, 1,000,000,000, add to 1. Then: (500,000,000 X 81) + 1= 40,500,000,001.
