Consider the subtraction problem, 2013 - 40, for which Allie gets the answer 1073. What is most likely Allie's misunderstanding, and, if uncorrected, what would Allie's answer be for 304 - 97 Select one: O a. Allie doesn't know her single-digit subtraction facts; she would say 304 -9- 25. O b. Allie doesn't know her single-digit subtraction facts; she would say 304 - 9 205. Oc. When Allie regroups she doesn't pay attention to place value; she would say 304 - 9 - 25. O d. When Allie regroups she doesn't pay attention to place value; she would say 304 -9- 205. O e. None of alternatives a-d are correct.
