This short math challenge tests one basic rule: multiplication comes before addition. The expression is 12 + 6 × 0 + 3.
Answer: 15.
First calculate 6 × 0. Any number multiplied by zero equals zero, so that part disappears. The expression becomes 12 + 0 + 3. Adding the remaining numbers gives 15.
If you simply work from left to right, you can end up with the wrong result. Following the standard order of operations makes the solution quick: multiplication first, then addition. The correct final answer is 15.
