4 The format of these examples is:
6 [valid Lineal syntax] = [familiar syntax] = ... = [answer]; [comment]
8 ie: The equivalent expressions after the first are not necessarily valid
9 syntax, though sometimes they are.
12 Infix notation is obviously more natural for mathematics; it provides
13 some shortcuts as well. First and foremost, a blank space generally
14 implies multiplication.
17 2 3 = 2*3 = 6; though it's ugly without the operator.
19 A space can also imply a function call.
21 rref A = rref(A) = rrefA
23 ------------------------------------------------------------------------
25 Some ambiguity can crop up; for example, let us work with the
26 determinant function and give its image for the 5x5 matrix /A/.
33 det 2*A = |2A| = 2 |A| = 32*3 = 96
35 det 2 A = |2| A = ERROR
37 det A 2 = |A| 2 = 3*2 = 6
