Start with the number of your birth month (January is 1, February is 2, and so on), add 9 squared, add 12 minus your birthday month number, multiply the value you have by itself, subtract 2.

I am so clueless about math I don’t know what this is called… the thing where you have 3 numbers and can then figure out the fourth value.
This is how I remember doing it in school, and I can calculate it, but cannot remember what it’s called. Also, is there a way to write it out?
