HP 28s - Algebraic Entry

It is nice to have the option to enter an entire expression as you would see it in a textbook, and have the calculator evaluate it. The disadvantage is not being able to see or store any of the intermediate calculations. Still a nice feature to have if one has the choice.

Is that Scp 168 the Sentient Calculator

Can I store a number quickly (similarly to how I store numbers in my HP 15c) and be able to recall that number in my HP 28 S?
