This math challenge looks incredibly simple, but one small detail can completely change your answer.
The expression is:
20 + 30 × 0 + 1
Remember to follow the order of operations. Multiplication comes before addition:
30 × 0 = 0
Now finish the remaining calculation:
20 + 0 + 1 = 21
A common mistake is thinking the ×0 makes the entire expression equal zero, but it only applies to the 30.
Answer: 21.
