Question

Modify the procedure of Gauss to find the sum.

Answer 1

which sum ? @Kainui

Answer 2

What's the sum? I can help you modify it. =P

Answer 3

1+2+3+...+175

Answer 4

Ok, well Gauss' method is to just add up the sum forwards and backwards like this:

So you just add the sum to itself backwards and you notice that you are really adding up the same number 175 times. \[\Large 2S=176*175\]

So now you can divide this by 2 to get the sum!
