I looked up the SAT's calculator policy:
Apparently they do NOT clear the calculator memory, so you could potentially store anything you could imagine in it. On the other hand, the test is designed so that students doing the problems by hand -- by thinking about them -- get higher scores than students who just blindly type things into their calculators.
Honestly, AznBoi, the easy way's not the best way. The more dependent on your calculator you allow yourself to become, the lower your score is likely to be.
