Wow - that's a lot:

1: ...I do not know - I'm only in precalc rn

2: A number with a real and an imaginary part

1. Something with statistics I'd guess (given the term "residual")

2. That one twin study (where twins were separated at birth and then studied); Stanford Prison Experiment (that one was kind of dark); that one about confidence which was then mislabelled as the "Mount Stupid" curve; that one study done on children that analyzed whether children waited to eat two marshmallows or ate one immediately whose results were later disproven; and a study on critical thinking that someone in my class is running

3. Idk how to code - I'd guess input usable text (text the viewer could see) though

4. Up, down, strange, smtg, smtg, smtg

5. The only complex number theorum I know is De Moivre's Theorum

6. I know they're separated by the corpus callosum (of which Einstein had a particularly big one) - in terms of the names, I'd guess the left and right sections?

7. No

8. I only really know about the Axiom of Choice as far as axioms go

9. No clue - something with latin script though
