Final answer:
Subtraction problem A, which is 8 − (−3), does not require zero pairs to solve using chips because it's equivalent to adding a positive number: 8 + 3 = 11.
Step-by-step explanation:
The question asks which subtraction problem does not require zero pairs to solve using chips. This can be determined by looking at the sign of the numbers involved in the subtraction. When using integer chips, zero pairs are typically needed when a positive number is subtracted from a negative number.
- A. 8 − (−2) = 8 + 3 = 11
- B. (−1) − 4 = (−1) + (−4) = −5
- C. (−3) − (−6) = (−3) + 6 = 3
- D. (−9) − (−5) = (−9) + 5 = −4
Looking at these options, we can see that options B, C, and D involve subtracting from negative numbers and thus could potentially require zero pairs. However, option A involves subtracting a negative number (which is the same as adding a positive number), so it does not require zero pairs. Therefore, the correct answer is option A where 8 minus negative 3 does not require zero pairs because it is simply 8 plus 3.
