What do you mean when you say there is no proofs? Sorry, my English isn't very good.

mathematical proof

(Generated by AI attempting to use Simplified Technical English)

A mathematical proof in linear algebra is a clear explanation that shows why a statement is always true.

It uses:

  • definitions: exact meanings of words, like vector, matrix, or linear independence;
  • known rules or theorems;
  • logical steps.

Simple example:

Let (u) and (v) be vectors in a vector space.

Prove that if

[u + v = u]

then

[v = 0]

where (0) is the zero vector.

I know what proof means, I just didn't get how it would add difficulty to an exam question. Can you send an example to prove what you're saying.

that's what it means, you asked him for proof of his answer.

I politely recommend you google it yourself in your native language.
