Numbers 
Use numerics, unless the number starts a sentence: "There were 99 red balloons", or "Ninety-nine red balloons..."

Use words for approximations. For example, 'Around two thousand international students study here' rather than 'Around 2,000 international students study here'.

Hyphenate written numbers, for example, 'twenty-one' rather than 'twenty one'.

Use commas to clarify numbers with 4 or more digits, for example, '2,300' rather than '2300'.
