sorry, my net is a bit slow. Here is it:

Answer 4

That's what the teacher wrote on the board. I really don't understand. At all.

Answer 5

Do you know what the symbols mean?

Answer 6

The topic is Direct proof and it's pure mathematics Unit 1.

Answer 7

Apparently U is an element of R (real number). That's all I know.

Answer 8

R means 'real number'. The E-like thing means 'is an element of the set'.

Answer 9

So far, so good.

Answer 10

U is a set of all possible values.

Answer 12

I think what your teacher is getting at is anything multiplied by 0 = 0? I'm not sure though.

Answer 13

That makes two of us :/

Answer 14

What grade are you in? This isn't university level stuff, is it?

Answer 15

It's Grade 12 (6th form). It's kind of similar to first year at a university though. Have you heard of CAPE exams? It's unit 1 Pure Mathematics.

Answer 16

Well, you can always ask your teacher tomorrow.

Answer 17

Oh, I will.
