Counting Positives and Negatives
If column A contains positive and negative numbers, you may need to count how many of each. You can use the following two formulas.
Positives
=COUNTIF(A:A,">0")
Negatives
=COUNTIF(A:A,"<0")
Zeroes
There may be zeroes as well. The formula to count them is
=COUNTIF(A:A,0)
