Answer 1

Ben wrote that Americans produce 6,550,000 cars instead of 5,650,000 cars. He made a mistake in writing the number at the start instead of 56, he wrote 65. But only writing this the error will be the difference of 900000 cars which is big figure. He can fix it by changing the figures in the number 6,550,000, 6 to 5 and the next 5 to 6, then it will be 5,650,000 which is the right.
