How much is 1 + 2 + (- 3) + (- 4) + 5 + 6 + (- 7) + (- 8) + 9 + 10. - 2008?
It's better to explain why
The rule of∵ sequence is that two odd numbers with the same sign are positive and even when they are paired, and negative when they are paired ∵ 2008 △ 2 = 1004, 2007 and 2008 are negative, and - 2007, - 2008 and ∵ 1 + 2 = 3, 3-3 = 0 - 4-7 = - 11, 5 + 6 = 11 - 11 + 11 = 0 - 8-11 = - 19, 9 + 10 = 19 - 19 + 19 = 0 ······ - 2004-2007 = - 4011, 2005 + 2006 =
How to calculate the numbers 34, 5, 6, 8, 9, 1 and 2 to get 2008
[(34 + 6) times (2 + 8) times 5] + 9-1 = 2008
