How would one go about improving their menthal arithmetic? I'm quite slow when it comes to doing calculations in my head and I have an upcoming examination that requires you to solve as many problems as you can under a harsh time limit. Has anyone ever tried improving mental arithmetic specifically before?

They sit there preaching their submissive methods of dealing with until they finally cack out.

Fucking shitty...

This needs to be to priority i mean what the fuck are we doing????
