Square[x] displays as square x.

Root[{f, c}] represents the exact root of the general equation f[x] = 0 near x=c. Root[{{f1, ..., fn}, {c1, ..., cn}}, j] represents the j ^th coordinate of the exact root of the system of equations {f1[x1, ..., xn] = 0, ..., fn[x1, ..., xn] = 0} near {x1, ..., xn}={c1, ..., cn}. Root[f, k] represents the exact k ^th root of the polynomial equation f[x] = 0. Root[{f1, f2, ...}, {k1, k2, ...}] represents the last coordinate of the exact vector {a1, a2, ...} such that ai is the ki ^th root of the polynomial equation fi[a1, ..., a i-1, x] = 0.

Graph[{e1, e2, ...}] yields a graph with edges ej. Graph[{v1, v2, ...}, {e1, e2, ...}] yields the graph with vertices vi and edges ej. Graph[{..., wi[vi, ...], ...}, {..., wj[ej, ...], ...}] yields a graph with vertex and edge properties defined by the symbolic wrappers wk. Graph[data] yields a graph from data.
