Great job completing level 1!

Now it's going to get a little bit harder.

 

Can you find the missing sign here?

11  ?  2 = 9

 

Is the missing sign + or -?

 

First, try the plus sign:

11 +  2 = 9

 

Then, try the minus sign:

11 - 2 = 9

 

The correct answer is the minus sign (-).

Let's get started with level 2. Good luck!
