This classic math riddle has been confusing people all over social media! It sounds like a simple calculation at first glance, but it is actually a clever puzzle that tests how carefully you read the wording.
The riddle asks: “80 divided by half plus 10 equals what?”
What makes this problem so tricky is the exact phrasing of “divided by half.” When we read this quickly, our brain often jumps to the phrase “divide in half.” If you divide 80 in half, you get 40. Adding 10 to that would give you 50, which is by far the most common wrong answer!
However, dividing by half means dividing by the fraction 1/2 (or 0.5). Mathematically, when you divide a number by a half, it is the exact same as multiplying it by two.
So, 80 divided by 1/2 equals 160.
Once you have that correct first step, the rest is easy. You simply take your 160 and add the final 10 to it to find your solution.
Answer: 170.
