The sentence "the product of 15 and the difference of 7 and 2" can be expressed mathematically in two parts:
- The difference of 7 and 2: This can be written as \( 7 - 2 \).
- The product of 15 and the result from the first part: This can be written as \( 15 \times (7 - 2) \).
Therefore, the two expressions that represent the sentence are:
- \( 7 - 2 \)
- \( 15 \times (7 - 2) \)
