常用的括号符号例如( )[ ]{ }可直接使用,但在较大的表达式显得不合适如: ( π 1 + 2 x ) n ( \frac{\pi}{1+\tfrac{2}{x}} )^n (1+x2π)n

所以一般用 \left(,\right)表示 ( π 1 + 2 x ) n \left( \frac{\pi}{1+\frac{2}{x}} \right)^n (1+x2π)n

含义符号语法备注可直接符号 ( a b ) , [ a b ] , { a b } ∣ a b ∣ \left( \frac{a}{b} \right),\left[ \frac{a}{b} \right],\left\{ \frac{a}{b} \right\}\left| \frac{a}{b} \right| (ba),[ba],{ba}∣ ∣ba∣ ∣\left( \frac{a}{b} \right) \left[ \frac{a}{b} \right] \left{ \frac{a}{b} \right}\left| \frac{a}{b} \right|角括号 ⟨ a b ⟩ \left\langle \frac{a}{b} \right\rangle ⟨ba⟩\left\langle \frac{a}{b} \right\rangle取消一侧括号显示 A B } → X \left. \frac{A}{B} \right\} \to X BA}→X\left. \frac{A}{B} \right} \to X在取消显示的一侧加上"."括号大小 ( ( ( ( ( ( \bigl( \Bigl( \biggl( \Biggl( ((((( ] ] ] ] ] \Biggr] \biggr] \Bigr] \bigr] ] ]]]]](\bigl( \Bigl( \biggl( \Biggl(\Biggr] \biggr] \Bigr] \bigr] ]普通{\color{Bluegreen}-b}\pm\sqrt{\color{Red}b^2-4ac}}{\color{Green}2a } {\color{Bluegreen}-b}\pm\sqrt{\color{Red}b^2-4ac}}{\color{Green}2a }
