Seconded. In fact, the natural answer to “how do I learn to prove” or “how do I understand mathematical notation” is that you do it by learning mathematics. In mathematics, it’s important, for example, to see how things are connected, and that’s what proofs help with. Without this mathematics turns into a largely useless collection of facts - useless because an isolated fact or a formula can rarely be used as is.
