sigma is the short for sums
for example, lets say you want to add 1+2+3+4+5+6.................+99+100
it's a problem writing every single term, right?
so if the sum it's a pattern like the example above, you can write it in sigma notation
search it up on the internet and find some simple examples because i am not the best explainer in the world

Sigma is a Greek symbol used for many variables in mathematics and science. However, within statistics, the variance is sigma squared and it is always positive.

However, in discussing errors, one can consider adding or subtracting sigma, ie the error in our experiment is +/- one sigma from the population.
