Question

Definition of the span in linear algebra?

Answer 1

Algebra is: a generalization of arithmetic in which letters representing numbers are combined according to the rules of arithmetic
2 : any of various systems or branches of mathematics or logic concerned with the properties and relationships of abstract entities (as complex numbers, matrices, sets, vectors, groups, rings, or fields) manipulated in symbolic form under operations often analogous to those of arithmetic
Algebra is adding, subtracting, multipling, and dividing with variable and numbers!

there is a easier way to know what it is just think of the letter as something like a for apple here is a e.g

a=5 and p=6
a=apple and p = pear

2a+2p=22
this means 2xa which is 2x5 and 2xp which is 2x6

Answer 2

The set of all linear combinations of a set of linearly independent vectors is the span of that vector set.
