Bracket Placement
1. The given expression is $2 + 16 \div 2 + 6 = 4$ and we want to place one set of brackets to make this equation true.
2. First, let's understand the original expression without brackets:
$$2 + 16 \div 2 + 6 = 2 + 8 + 6 = 16$$
This is not equal to 4, so we need to insert brackets to change the order of operations.
3. Let's try placing brackets around $16 \div 2 + 6$:
$$2 + (16 \div 2 + 6) = 2 + (8 + 6) = 2 + 14 = 16$$
Not equal to 4.
4. Next, try brackets around $16 \div (2 + 6)$:
$$2 + 16 \div (2 + 6) = 2 + 16 \div 8 = 2 + 2 = 4$$
This satisfies the equation.
5. Therefore, the correct placement of brackets is:
$$2 + 16 \div (2 + 6) = 4$$
Final answer: Place the brackets as $16 \div (2 + 6)$ to make the equation true.
