也可以颠倒过来:anytext^{uptext}_{downtext}
还可以只加一种:anytext_{downtext}anytext^{uptext}

样例:
x 2 x^{2} ← x^{2}
H 2 O H_{2}O ← H_{2}O

2 3 \sqrt[3]{2} ← \sqrt[3]{2}
3 n \sqrt[n]{3} ← \sqrt[n]{3}

积分

基本格式:
\int_{积分下限}^{积分上限} \int_{积分下限}^{积分上限}
也可以颠倒过来:\int^{积分上限}_{积分下限}

样例:
8 3 x 3 d x \int^{3}_{8}x^3dx ← \int{3}_{8}x3dx

大型运算符

基本格式:(以连乘运算符为例)
\prod_{downtext}^{uptext} d o w n t e x t u p t e x t \prod_{downtext}^{uptext}
