12, 7, 4, 8, 6, 4, 8 First I have to put them in order: 4, 4, 6, 7, 8, 8, 12
 * My #'s**


 * Mean=** 4+4+6+7+8+8+12= 49÷7= 7 (the mean is 7)
 * Median=** 4, 4, 6, **7**, 8, 8, 12= 7 is the middle number (the median is 7)
 * Mode=** 4, 4, 6, 7, 8, 8, 12= 4 and 8 showed up the most (the modes are 4 & 8)

=__**Square Roots**__= //What is the square root of 30?//
 * Square Root-** The result of multiplying the number by itself
