Parentheses below the expression:

Key points:

Long arrow to the right:

Wave line:

Line break alignment of multi-line formula:

Square:, triangle:

\ Restrictions:

Use \limits to control whether the subscript is on the right side or on the top and bottom sides of the symbol. The mathematical symbols that support \ restrictions are:

Caret:, \overset{? }=

Insert the symbol:, \ underset {0 \ le j \ le k- 1} under the expression.

Line feed under the sum sign:, \ sum \ limits _ {\ substack {0

Degree:&; deg

Mini math formula:, \tiny f = a+b

Small mathematical formula: \ small f = a+b

Macro mathematical formula: \ big f = a+b
