Gathering the sum of negative numbers & positive numbers in a column

I have a column of variances, these contain both negative numbers and positive numbers.

I want to gather a sum of all the negative numbers and positive numbers separtely.

Basically saying all the positive overeages = this amount

And all the negative shortages = this amount.

you can see the attached sample.

thanks for any help.

=SUMIF(B:B,">="&0)

and

=SUMIF(B:B,"<"&0)

=SUMIF(B3:B24,">0",B3:B24) for the positive

=SUMIF(B3:B24,"<0",B3:B24) for the negative

Adjust ranges as needed for actual data ranges....
