|-x| = |+x| \qquad \left|-x\right| = \left|+x\right| \qquad \lfloor -x\rfloor = -\lceil+x\rceil

TeXbook p. 172

x_1 = \cdots = x_n = 0 \qquad A_1 \times \cdots \times A_n \qquad f(x_1,\ldots,x_n)

TeXbook p. 174

\bigl\{\,\bigl(x,f(x)\bigr)\bigm| x\in D\,\bigr\} \qquad \bigl\{\,x^3\bigm| h(x)\in\{-1,0,+1\}\,\bigr\}

TeXbook p. 176

A = \pmatrix{x-\lambda & 1 & 0\cr 0 & x-\lambda & 1\cr 0 & 0 & x-\lambda\cr} \qquad\qquad \left\lgroup\matrix{a&b&c\cr d&e&f}\right\rgroup \left\lgroup\matrix{u&x\cr v&y\cr w&z}\right\rgroup

TeXbook p. 177
A = \pmatrix{a_{11} & a_{12} & \ldots & a_{1n}\cr a_{21} & a_{22} & \ldots & a_{2n}\cr \vdots & \vdots & \ddots & \vdots\cr a_{m1} & a_{m2} & \ldots & a_{mn}} \qquad\qquad \pmatrix{y_1\cr\vdots\cr y_k}
