Career Advice How much Maths is in ChemEng?

Hii, im a year 12 student who is currently thinking about what course i should do. And im stuck between Maths and ChemEng. I only recently discovered a Maths course is just mainly proofs which isnt exactly what i was looking for. I absolutely love Maths and i really want to continue it in the future and I think the maths in engineering is my best bet as it is applied. But the thing is, i dont do physics so the engineering courses i could do are very limited. So i can really only apply for ChemEng.

My main question is “Is chemical engineering majority maths and roughly what percentage of the course is just maths?”

I would say there is a lot of maths in chemical engineering, but it is mostly the sensible kind of maths like calculus and the alright kind of maths like statistics, not the crazy maths that people into physics or electronic and software engineering have to deal with.

Out of curiosity, what is the crazy math exactly?

The maths that stops being about fundamentally sensible, tangible things like rates of change and adding stuff up in different ways, and starts going into things like imaginary numbers or the Laplace transform or wave functions or operators.
