Answer:
is there more to the question
Answer: 15 - (6 + 1) + 30 ÷ (3 × 2)
Step-by-step explanation:
The simplest way is just to [try check and revise]. Place parentheses on each two numbers and try.
However, there is a somewhat trick involved.
Normally, when a question asks for adding parentheses, the parentheses are normally placed on two numbers that don't usually operate together.
- For example, in this question, [15 - 6 + 1]. Normally, is should be 15-6 which is 9. Then 9+1 is 10. Also, usually when you add parentheses on -6+1, it will change signs into -(6-1). But, in this question, when we add parentheses, signs don't change. So it is -(6+1).
Hope this helps!! :)
