Math shortcuts
As well as the math template, there are other similar screens that oer a palette of special characters. For
example, pressing displays the special symbols palette, shown in the following gure.
Select a character by tapping it (or scrolling to it and pressing
).
A similar palette—the relations palette—is displayed if you press . The palette displays
operators useful in math and programming. Again, just tap the character you want.
Other math shortcut keys include . Pressing this key inserts an X, T, θ, or N depending on what app
you are using. (This is explained further in the chapters describing the apps.)
Similarly, pressing enters a degree, minute, or second character. It enters ° if no degree
symbol is part of your expression; enters ′ if the previous entry is a value in degrees; and enters ″ if the
previous entry is a value in minutes.
Thus, entering 36 40 20 yields 36°40′ 20 ″. See Hexagesimal
numbers on page 15 for more information.
