Comparing Approximate to Exact "Error": Subtract Approximate value from Exact value. The absolute value of a number is the value of the positive value of the number, whether it's positive or negative. However if percent error is equal to 100 percent or -100 percent, then there is only one calculated solution and one solution of infinity. c.) the percentage error in the measured length of the field Answer: a.) The absolute error in the length of the field is 8 feet. visit
