Neha was solving a problem in which subtraction of 673–257 was required. She said, "257 plus 100 will be 357, 457, 557, 657. So, 257 plus 400 is 657". "Now 657 plus 10 is 667, 677, so, 657 plus 20 is 677 and 4 less in 677 is 673. "Therefore, 400 plus 20 minus 4 is 416". Hence 673–257 is 416. Which of the following statements is most appropriate for the strategy of Neha?
