Similarly, Signs have also genders.
From Aries to Pisces signs are Male and Female alternatively.
That means, odd signs (1st, 3rd, 5th ...) are Masculine and even signs (2nd, 4th, 6th ...) are Feminine.
We know that lord of both Aries and Scorpio is Mars only. But Aries is of Masculine nature and Scorpio is Feminine nature.
So we can represent Aries as (Ma+) and Scorpio as (Ma-), similarly Gemini as (Me+) and Virgo as (Me-), Libra as (Ve+) and Taurus as (Ve-)... And so on.
