Here are the numerical expressions for each problem, broken down step by step.
1. Twice as many as the sum of 7 and 8
* First, find the "sum of 7 and 8," which means adding them together: $(7 + 8)$.
* Next, "twice as many" means multiplying that result by 2.
* Expression: $2 \times (7 + 8)$
2. Subtract 17 from the product of 8 and 6
* First, find the "product of 8 and 6," which means multiplying them: $(8 \times 6)$.
* Next, "subtract 17 from" that result means you take the product and minus 17.
* Expression: $(8 \times 6) - 17$
3. 6 times as many as the difference between 8 and 2
* First, find the "difference between 8 and 2," which means subtracting: $(8 - 2)$.
* Next, "6 times as many" means multiplying that result by 6.
* Expression: $6 \times (8 - 2)$
4. Add 23 to the difference between 7 and 5
* First, find the "difference between 7 and 5," which means subtracting: $(7 - 5)$.
* Next, "add 23 to" that result means you add 23 to the difference.
* Expression: $23 + (7 - 5)$
5. 4 times as many as the product of 2 and 3
* First, find the "product of 2 and 3," which means multiplying them: $(2 \times 3)$.
* Next, "4 times as many" means multiplying that result by 4.
* Expression: $4 \times (2 \times 3)$
Final Answer:
1. $2 \times (7 + 8)$
2. $(8 \times 6) - 17$
3. $6 \times (8 - 2)$
4. $23 + (7 - 5)$
5. $4 \times (2 \times 3)$
