OneNote Linear Format Equations

Press ALT+=, and then type the equation.

Type equations in linear format
To align an equation array, you can use @ and &, as in the following:

eqarray(x+1&=2@1+2+3+y&=z@3/x&=6)<space>

which resolves to this:

Examples:
 Example Linear format Built-up format Vectors (abc) ec (abc)hat Boxed formula ect(a/b) Brackets (a+b/c) {a+b/c} Brackets with separators {a/b barx+y bar} Fractions a/(b+c) LeftSubSup _a^bx Limit lim_(n->infty)n Matrix (matrix(a&b@&c&d)) Nary iint_(a=0)^inftya Over/Underbar overbar(abc) overbrace(a+b) Radicals sqrt(5&a^2)
Note:  When an example is followed by two consecutive spaces, the first space resolves the typed text into the equation, and the second space builds it up.
