To people who are viewing this I am a mechatronicist (Engineering, coding, science blah blah!) so I can give a hand with things and I am also pretty good at maths but I haven't done much on that subject aside from things such as algebra and indeces but it's still useful if you get stuck. I can also make calculators which can calculate pretty much everything such as area or fuel efficiency with a few lines of code and I can custom make them because some aren't on the internet! PM if you need a hand and I probably can help...
