Are you smarter than a fifth grader? No, we're not offering a cash prize if you can prove it. But after struggling with these "easy" math questions we'd like to see how many you can solve.

We promise you don't need a calculator for any questions, but keep a **pencil and paper** handy because **the answers are on the last page!**

## 1. Let's start simple

A study in Japan found that 60% of people in their 20s got this question right, compared to 90% of older generations. We're not sure what being a millennial has to do with math, but see if you can solve this equation.

## 2. What's the ?

The aim of this puzzle is to solve what number is in the ? space. Yes, it's really that simple. And no, we can't give you any other clues.

## 3. The bat and the ball

This is an oldie but a goodie:

A baseball bat with a ball costs **$1.10**. The bat **cost $1 more** than the ball. **How much does the ball cost?**

Which is the best answer?

## 5. Here's a head-scratcher

Take a look at this equation and see if you can solve it:

What's the answer?

## 6. Lily pad logic

There's a lake with a patch of lily pads growing on it. Every day, the patch **doubles in size**. If it takes **48 days** to cover the whole lake, how long would it take to cover just half of the lake?

**If those aren't tough enough we have more questions, and of course the answers are on the last page.**
