|==Greek Letters== Write "alpha", "beta", or "gamma" in lowercase.

Example.

• alpha → alpha
• beta → beta
• chi → chi
• delta → delta
• epsilon → epsilon
• gamma → gamma
• eta → eta
• and so on.

Super/subscripts

Use "_" for subscripts, "^" for superscripts. To show both, write the longer super/sub-script first. Some word must follow after a space when both ^ and _ are used.

Example.

• _1^2 (next word) → _1^2 (next word)
• D_{10}^{20} (next word) → D_{10}^{20} (next word)
• D_{10000}^{1} (next word) → D_{10000}^{1} (next word)
• D^{10000}_{1} (next word) → D^{10000}_{1} (next word)
• D^{10}_{10000} (bad example) → D^{10}_{10000} (bad example)
• D_1 → D_1
• D^2 → D^2
• Delta^{12.13} → Delta^{12.13}
