Well, the rule of rounding is: if the number is higher than 5, or 5, you round up, and if it is lower than 5, you round down. 5 gets rounded up, so that makes 7 and eight, and eight is higher than 5 so it also gets rounded up, so that would be 6,322. If the decimals were lower, than you would have gotten 6,320, but we rounded up, so 6,322 is the correct answer. Did this help?
It would be -50 because the rule is subtract by 2 then 4 then 6 then 8 and etc.
