Yes, the correct answer is 9.
To solve this correctly, we need to follow the Order of Operations, also known as PEMDAS or BODMAS. This rule ensures that every mathematical expression is solved in the correct and consistent way.

The Problem:
15 – 3 × 4 + 6
STEP 1: Handle Multiplication First
According to the order of operations, multiplication comes before addition and subtraction.
So we first calculate:
3 × 4 = 12

Now the expression becomes:
15 – 12 + 6
STEP 2: Work Left to Right
Once multiplication is completed, we only have subtraction and addition left. These are solved from left to right.
First: 15 – 12 = 3
Then: 3 + 6 = 9
Final Answer: 9

Many people make mistakes with this type of problem by solving strictly from left to right without applying the correct order of operations. For example, they might incorrectly do 15 – 3 first, which changes the entire result.
If done incorrectly:
15 – 3 = 12
12 × 4 = 48
48 + 6 = 54 ❌
This shows how important it is to follow the correct mathematical rules. Multiplication always takes priority over addition and subtraction unless parentheses indicate otherwise.
