Arrange the terms in ascending order.
The maximum value is the largest value in the arranged data set.
The absolute value is the distance between a number and zero. The distance between and is .
Add and to get .
To calculate the second bound option, sum the absolute values of the coefficients from the list of coefficients. If the sum is greater than , use that number. If not, use .
