Check your grammar. I can't undersrand it. I'll just answer the rounded off part.

Rounded off to the nearest thousands. The answer is still 6000 because number 6 is yhe thousands place and if you look beside the number (right) it's number zero and the rule of rounding off if the right number of the underlined digit is 0,1,2,3,4 you will NOT add +1 you'll just remain the number itself and if yhe right number of the underlined digit is 5,6,7,8,9 you will round up (add +1) of the underlined digit. And just put zero (0) to it's right.
