Who discovered zero and who is considered the Mother or Queen of Maths?

The concept and use of zero as a number originated in India, with Brahmagupta often credited with its formal definition and rules. While there isn't one universally recognized "Mother of Maths" or "Queen of Math," Hypatia of Alexandria is frequently cited as one of the earliest known female mathematicians. Other notable female mathematicians like Shakuntala Devi are sometimes referred to as the "math lady of India" or "human computer".
