Use your math skills to find the value of each symbol and the ? in the puzzle below.
The nintendo controller in the first and second rows tells us that it is equal to 11.
This means the pacman is also 11 since 11 x 11 = 121.
Which means the gameboy thing is 20 - 11, which equals 9.
Then finally we see that the xbox controller - the gameboy, which is 9, equates to 7. This means the xbox controller is 16.
Now we know that the nintendo controller and the xbox controller is 11, and 16.
Which finally gives us the answer of 176. :)
