Good day :) I am a college student. I cant find the right JavaScript code for my thesis. how can make image disappear by just answering a simple mathematical question by just typing it?i want to disappear the ant by solving the math problem above it.

the scenario is an ant is carrying a math operation above it. in order to kill the ant, i will answer the math operation that ant carries. here is the image.

any recommendation will be highly appreciated. thanks a lot :D

do you (code-wise) have a connection between the ant (image) and the math?

I am the author of that question.i cant log in to my account. Yes, there must be a connection between the ants and math. If u answer the math correctly,the ants will disapear . Else, the ants will go to your base and destroy it. but i cant search my code.
