How to add 1 if the text= a specific value (value example: 60+)

[Quillow]

Hi! I'm having issues. I have a list of values:

<19
20's
30's
40's
50's
60+

And they are randomly dispersed through the column, I want to add only the values that are equal to those to create a total.

So I want to add all of the <19 and have that represented by a number.

Like if the cell equals <19 then add 1 to come up with a total. So if there are five <19 values in the column then the total would be 5.

Is this doable?

Try the countif function

=COUNTIF(A1:A100,"<19")

Works perfectly! Thank you very much!!

Okay, another question. What if I have a column beside the original column that has a number. So say it's like this:
1 <19
2 50's
1 <19
3 20's

I want to add the amount of 20 year olds so you'd need to add cell b3 if cell c3=20's
How do I do that?
