Just press the clear (C) button. That clears everything.

Why, oh why, isn’t there a clear error button on calculator. Or is there a simple way to do this?

They work the same as they do on any calculator. M+ adds to the number in memory, M- subtracts from it, MR recalls memory and MC clears it.
So you could do MC to clear. Then 2 x 3 = M+ to put 6 into memory. Then 3 x 3 = M+ to add 9 to it for 15. Then 5 x 3 = M+ to add another 15 to memory. Pressing MR would then give you 30.

If you turn the phone on it’s side while in Calculator – viola! A full scientific calculator appears – it’s not so basic after all…

Enjoy!
