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!
