Num lock. The Num Lock key exists because earlier 84-key IBM PC keyboards did not have cursor control or arrows separate from the numeric keypad.

The most common rule. The most common and frequently used rule for writing numbers in APA style is determined by whether the number is under 10. All those numbers should be written out in word form, such as four or seven. A number 10 and above is written as a numeral, such as 10, 17, 233.

If you begin a sentence with a number, spell it out, even if it is a date or other number that uses more than two words.When using large numbers, as long as they do not start the sentence, you can use a combination of numerals and words, such as 3.6 billion.. Write out spans of time such as sixteenth century..ormatting. Use the same structure for all portions of ideas that demonstrate a comparative relationship, such as 4 of the 310 members.. Use commas between every three digits from the right in large numerals (1,000 and 352,000,000). Type symbols such as $ for money amounts and percentages in MLA.
