Math Problem Statement
Solution
The given expression is:
We need to insert parentheses so that:
- The first operation is addition.
- The second operation is multiplication.
- The third operation is division.
Let's break down the solution:
To ensure that the first operation is addition, the addition part of the expression must be in parentheses:
This setup ensures that:
- First: The multiplication is done because it is inside parentheses.
- Second: The addition is done after the result of multiplication.
- Third: The division is performed after multiplication and addition.
Thus, the correct expression is:
This satisfies the condition that:
(a) The first operation is addition.
(b) The second operation is multiplication.
(c) The third operation is division.
