Beyond the very very basic level, some skills are a must to have to follow most of the content linked at this website:
Single-variable differentiation and integration understanding is needed to get off the ground, but multivariable calculus and linear algebra will quickly come in handy. Furthermore, probability and statistics will be needed to understand some high-level concepts.
If you already know high-school-level math, you should be able to learn calculus (that's the name for a branch of math encompassing differentiation, integration, etc.) from this online course:
Delft University of Technology: Calculus I: From Functions to Differential Equations, delivered for free on edX online platform -- https://www.edx.org/learn/math/delft-university-of-technology-mastering-mathematics-for-engineers-calculus-1There is also a continuation of this course that considers multivariable calculus:
Delft University of Technology: Calculus II: Multivariable Functions -- https://www.edx.org/learn/math/delft-university-of-technology-mastering-mathematics-for-engineers-calculus-2If you prefer learning from a book, many engineering university programs use this book as a calculus course basis:
Stewart, James, Dan Clegg, and Saleem Watson. Calculus : Early Transcendentals.
For aerospace, the following sciences, and listed branches in particular, are core of engineering considerations:
Physics
Classical Mechanics
Thermodynamics
Chemistry
Combustion processes -- used mainly in propulsion engineering
This is the language in which most of the content recommended here is provided. Thus, ability or persistence
Currently, it is also the language in which most of the advances in aerospace engineering (and probably a majority of other fields of science and engineering) are communicated. We don't provide any resources to learn it as we don't any that let you learn without assumption of any other language knowledge.
The field of aerospace engineering is mainly about the problems related to flight and, as you probably already know, there are two main environments in which you can fly:
Earth atmosphere - covered by Aeronautical Engineering
Outer space (commonly, but wrongly, called cosmos) - covered by Astronautical Engineering
Actually, there are also atmospheres of all other celestial bodies, but let's stay with these two for now.
Many engineering problems are very distinct for these two domains, but they also share a lot --- probably the only reason why the common name for these two is still in use.
The diagram below gives a non-exhaustive outline of how AE is divided and what are the main engineering disciplines outside aerospace that are a core part of many aerospace engineering designs.
