What’s the total?

This simple-looking math puzzle has gone viral for one reason: it tricks a lot of people. Even confident problem-solvers often blurt out the wrong answer without realizing where they slipped.

In fact, studies and social media polls suggest that around 40% of people get this wrong on their first try.

So—what did you get?

Many people confidently answer 5000.

But let’s slow it down and do it properly.

Step-by-step solution:

First, group the thousands:

1000 + 1000 + 1000 + 1000 = 4000

Now add the smaller numbers:

40 + 30 + 20 + 10 = 100

Finally, combine them:

4000 + 100 = 4100

✅ The correct answer is 4100.

Surprised? If you don’t believe it, feel free to double-check with a calculator—but your brain can handle it just fine when you slow down.
