You really don’t. There’s many resources out there that involves minimal math.
To calculate bullet trajectory (without math) you can use this resourced called “FastCast”, it has bullet physics (as highlighted by the post)
I’m no expert (I really haven’t used this module), but if you do need help, maybe @EtiTheSpirit can provide you with further support. The docs should help you initially set this up.
For me personally, I learned some useful math by teaching myself, so you can be in a lower math level and still learn some useful programming concepts.
