The key is understanding what “divided by half” actually means. Dividing by one-half is not the same as dividing by two. Instead, dividing a number by 1/2 is equivalent to multiplying it by two. Therefore, 13 divided by 1/2 equals 26.
The order of operations also matters. Division must be completed before addition or subtraction, so the expression becomes 93 − 26 + 4. Working from left to right, 93 minus 26 equals 67, and adding 4 gives 71.
That means the correct answer to the puzzle is 71. The challenge demonstrates how simple wording and a small misunderstanding of fractions can completely change an answer, making an apparently straightforward calculation surprisingly effective at catching people off guard.
