f) 7 × (5 + 3)

Explanation:

Step1: Analyze first question

The question asks for 4 multiplied by the difference of 10 and 7. First, the difference of 10 and 7 is $10-7$, then multiply by 4: $4\times(10-7)$.

Step2: Analyze second question

The question asks for 7 added to the product of 5 and 3. The product of 5 and 3 is $5\times3$, then add 7: $(5\times3)+7$, which is equivalent to $7+(5\times3)$.

Answer:

1. A) $4 \times (10 - 7)$
2. A) $(5 \times 3) + 7$, E) $7 + (5 \times 3)$
