1. **Calculate the difference between the circled digits (9 and 3) in 1249326:** The circled digits are 9 and 3. The difference is calculated as: $$9 - 3 = 6$$ 2. **Find approximately how many hundred dollars worth of grocery mom bought from $586.40:** We divide 586.40 by 100 to get the number of hundred-dollar units: $$\frac{586.40}{100} = 5.864$$ Approximately, mom bought about 6 hundred dollars worth of groceries. 3. **Identify the value of the carry digit 1 from addition of 7 and 9 in the addition problem:** Adding 7 and 9 gives 16. The 6 is written in the current column and the 1 is carried to the next (left) column. The value of the carry digit 1 is thus: $$1 \times 10 = 10$$ The carry digit represents 10 in the next column's place value. **Final answers:** - Difference between circled digits: 6 - Approximate hundreds of dollars spent: 6 - Value of carry digit 1 in addition: 10
