measure of central tendency  
  Mean, median, and mode are all measures of central tendency, reflecting special statistical information about a set of data.
median  
  The middle number of an ordered set of data.  If there is no distinct middle, then the average of the two middle numbers is the median.
midpoint  
  A point that divides a segment into two segments of equal length.  For example, D is the midpoint of BC  in pic at right.
   
mixed number (fraction)

mode  
  The number or numbers that occur the most often within a set of data.  There may be more than one mode for a set of data.
multiple  
  The product of a whole number and any other (nonzero) whole number.  For example, 15 is a multiple of 5.
multiplication (·)  
  An operation that reflects repeated addition.  For example, 3 · 4 = 4 + 4 + 4.
multiplicative identity  
  The multiplicative identity property states that multiplying any expression by 1 leaves the expression unchanged.  That is, a(1) = a.  For example, 437 x · 1 = 437x.
