Baby steps my friend. Start with understanding addition, multiplication and powers. Then go for fractions and algebra.

2+2+2+2

Is the same as:

2×4

Is the same as:

2×2×2

Is the same as:

2^3

And so on. Play with the basic basic stuff until you understand it. I know it feels weird and dumb, but it is Essential to understand the basics before you go on further.

I failed basic highschool math, believed i was dumb etc. I decided to go back at it a few years later, and started at the 1st grade stuff. 5 years later and i passed multivariable calculus / calc 3. And graduated with a bachelor in engineering with a GPA at 4.6
