I’ve got lazy with this these days mate, i just use my phone calculator. I used to add them in my head all the time but then i couldn’t be arsed one time, probably was ill or hungover and saw it was just as easy to calculate it without taxing my brain lol The world and his dog used to say “you just use a calculator” so why not in the end eh. Over the time i used to do it in my head i did get a couple wrong but try telling people that you don’t use a calculator because you got some wrong sometimes and they just throw back that you got them wrong on purpose lmao The world we live in.
