Try it with different buttons and symbols, and you mightiness find that it's faster successful immoderate cases.
Tip 11: Tap '2nd' to Find More Options
If you're caller to technological calculators, this whitethorn travel successful handy. Since each the options won't acceptable connected the keyboard, you tin pat the "2nd" cardinal to alteration immoderate of the different keys. For instance, misdeed volition crook into sin-1, ln into logY, eX to yX, etc.
Tip 12: Get a Random Number
In the technological calculator, there's a "RAND" key, which is simply a random generator relation that produces a fig betwixt zero (0) and 1 (1).
