But some publications spell out ten, others use 10. When numbers and figures are used in the same sentence or paragraph, books usually make all figures, while magazines and newspapers follow the appropriate rule for each. 1998 is not a presidential election year. Use figures for all building numbers. Follow the general number rule for numbered streets and avenues.
Some publications use figures for all numbers in an address.

Use only those abbreviations that are common and readily understood by your readers. Check style book for the correct abbreviation to use and what should be used on first reference.
