I don't truly understand maths

Throughout my time in math I always just did the math without questioning how I got there without caring about the rationale as long as I knew how to do the math and so far I have taken up calc 2. I have noticed throughout my time mathematics I do not understand what I am actually doing. I understand how to get the answer, but recently I asked myself why am I getting this answer. What is the answer for, and how do I even apply the formulas to real life? Not sure if this is a common thing or is it just me.
