Answer 11

Thank you! Now, I can read it :)

Answer 12

Please someone help.. I'm in connections academy.

Answer 13

Cool!! @cakemeister

Answer 14

I'm checking your answers with the ones I'm getting

Answer 15

Okay, I got the same answers for the ones you gave except for #1

Answer 16

Okay :D what is number 1?

Answer 17

no, it's right. My bad. I didn't look at the right number. >.<

Answer 18

There is nothing in between #8. It's just standard multiplication, right?

Answer 19

In between the parenthesis, yes :)
