Answer:
A. Understand how to do the math problem
Step-by-step explanation:
When someone says "Did you get how to do that math problem? " they're asking you if you understood it. Not to keep up with the math notes or pick it up, there isn't even a mention of any notes in that sentence.
For example:
"Hey Mitchell, did you get how to do that math problem on the geometry quiz?"
" Yeah, I used the Pythagorean theorem"
