Explanation:
During the time of his childhood, Alexander spent a good percentage of his childhood being taught by his personal tutor, Aristotle. Aristotle taught him mathematics, reading, writing and how to play the lyre. As he grew older, Aristotle would go on to teach him how to ride a horse, battle, and hunt. This is during the time when Alexander found his favorite horse, Bucephalas that would go on to serve him for many years.
Alexander met a lot of his future generals (such as Ptolemy and Cassandra, etc.) while attending school.
Towards the end of his childhood and the beginning of manlyhood, at the ripe age of 16, his father left him in charge of their kingdom while he waged war against Byzantion. Although, while the King’s absence, the Thracian Maedi charged against Macedonia and went in full force knowing of the king’s absence. Despite of this, Alexander The Great took full control and acted quickly which drove the opponent away from Macedonia.
