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. Most earlier computer keyboards had separate number keys and cursor control keys; however, to reduce cost, IBM chose to combine the two in their early PC keyboards.
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.
Thanks! A. No commas should be used when numbers are written out: 103,000 = one hundred three thousand. The longer the number, the more awkward it may seem, but commas would make the number look like a series of smaller numbers, something that doesnât happen with numerals because there are no spaces, for one thing.
