@Liam, what are opposite vectors? Do you know how to express an example of them here?

Liam · Answer

Opposite vectors are two vectors with same magnitude but opposite direction.

Hero · Answer

Yes, but how would you express for example in mathematical form a vector and its opposite?

Liam · Answer

So vector A and vector -A are opposite. 
|dw:1525904534797:dw|
^Assuming those are the same size

Hero · Answer

Okay, so as an example you have $\large\vec{a}$ and $-\large{\vec{a}}$ and then you add them together. What do you think will be the result of $\large\vec{a} + (-\large{\vec{a}})$ ?

Hero · Answer

Consider, for example what happens when you add $5 + (-5)$

Liam · Answer

Becomes 0

Hero · Answer

Yes correct.

Liam · Answer

Oh so the resultant is the zero vector

Hero · Answer

Exactly

Liam · Answer

Tysm!! Can you help me on a few more?

Hero · Answer

IDK, I'm quite busy with a few projects TBH

Liam · Answer

Okay then (:
