Calculator that does ….

Hey guys,
From all the websites I know of I always use this one only for help lol.
So my bro during his Math lessons gets told off for not showing his workings as he just writes the ANS as the calculator shows. Considering I’m a lazy sod I thought what would I do? find a calculator that shows the workings example fractions must be shown what was divided into what, what lcm and so on, must as well do binary with 2’s compliment and the other thing (forgot what he said it was to do with binarys).
well I’m sure you math students know what is needed to be shown (workings) -fractions BODMAS/mixed operations
-binary
-solving linear equations
-algebraic techniques
-Indices and standard form
-percentages & ratios
-matrices etc…..
Im sure their is more topics as I just rummaged through his ””’NOTES””” which look like noodles
EDIT: is there a calculator that shows the workings to get to the ans ?
