Angle brackets ⟨ ⟩ are used in group theory and commutative algebra to specify group presentations, and to denote the subgroup or ideal generated by a collection of elements.
How do you type angle brackets?
The angle brackets () are between the “m” & “?/” keys on the keyboard. You need to press the “Shift” key & the “” keys to type them. The square brackets ([]) are between the “p” & the “|” (pipe/backslash) keys.
