To solve the expression and see if it equals 35, we can follow the correct order of operations, which is commonly remembered by the acronym PEMDAS:

1. **P**arentheses
2. **E**xponents
3. **M**ultiplication and **D**ivision (from left to right)
4. **A**ddition and **S**ubtraction (from left to right)

Given the expression: 

\[ 15 + 2 \times 12 - 4 \]

1. **Multiplication first**:
   \[ 2 \times 12 = 24 \]

2. **Substitute the result back into the expression**:
   \[ 15 + 24 - 4 \]

3. **Addition and subtraction next, from left to right**:
   \[ 15 + 24 = 39 \]
   \[ 39 - 4 = 35 \]

Thus, the correct evaluation gives:

\[ 15 + 2 \times 12 - 4 = 35 \]

This confirms that the expression is already equal to 35, so no parentheses need to be added to change the result.

**Tip:** Always perform multiplication and division before addition and subtraction unless parentheses indicate otherwise.
