1. AP on Hyphenated Prefixes
Always use a hyphen with “all-”:
all-knowing, all-seeing, all-caring Rushbo
Hyphenate “anti-” words with some exceptions: see Stylebook for list
“Co-” is generally hyphenated for job titles, no hyphen for most of rest. Stylebook lists exceptions.
“Ex” is hyphenated when it means “former,” as in ex-president. No hyphen when it’s part of a verb.

2. More AP Hyphens
“In” takes no hyphen if it means “not”: intolerable. Takes hyphen in compound adjectives: in-depth. Always a hyphen if used as a suffix: break-in.
“Post-” A jumble of exceptions. Postwar, post-mortem. Look it up.
“Pro-” Hyphenate only when it means showing support: pro-war, profile.
“Re” is hyphenated when the next letter is an “e”. See Stylebook for other rules.

3. AP on Numbers
Don’t start sentences with big numbers; spell them out if you must.
In proper names, use what they use.
Spell out one-nine, then use numbers.
Use 1st, 2nd, etc. in forming titles.
Dates never take suffixes:
Right: Dec. 2
Wrong: Dec. 2nd

4. More AP Numbers
Don’t use more than two decimal points in text unless there’s a special reason.
For money, the whole number up to 999,999, then words and numbers:
999,999
1 million
1.36 million
Instead of a “-” minus sign, use “minus”.

5. Yet More AP Numbers
U.S. Highway 1, state road FM2222, Interstate Highway 35.
Use numbers when measuring dimension, formulas and speeds. Folo standard rule with distances.
The tornado’s path was 2 miles wide.
The group drove five miles to safety.
6.5 percent; 0.5 percent.

6. It Never Stops!
Express ratios this way: a 2-1 ratio; the ratio was 2-to-1. (Note hyphens.)
Use figures exclusively for scores, sizes, telephone numbers, weights.
All temps are figures except for zero.
All times are figures except noon and midnight: 10:30 a.m., noon.
Years are always figures, and a year can start a sentence (though that sucks).
