Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh. 
Salaah was incumbent upon you from the time you attained puberty. You will have to make up all the daily Fardh and Wajib salaah that you have missed since the time you reached puberty.[1]
