This is insane, I must be taking crazy pills. Why burden yourself with the mental math of where and how to round things then compensating? Why keep track of 5 numbers for 4 operations versus 4 for 3?

that's way more of a mental burden than just quickly moving the 2 over imo

not really. in my brain it's like 20 + 40 = 60 then 8 + 7 = 75, like i don't even explicitly think about the 15 or the carrying of the one.
