		 When values are not equal to each other, one must be larger or smaller than the other (if numbers), or one must fall before (smaller) or after (larger) the other in alphabetical order.  > and < are the symbols for Greater-Than and Less-Than.  

88 < 100 , or 88 is less than 100.  

Sometimes, you want to find data where a certain field is 'at or below' a certain value, like 'purchase orders whose values are 500 dollars or less.' This is Less-Than-Or-Equal-To, or <=.  And of course, there is a corresponding Greater-Than-Or-Equal-To, >= .
