To sum the numbers 1.53, .006, .1223; which are correct as they are given. Find absolute and relative error.

Computing x1x2 and x1/x2 for x1=2.48, x2=3.4415, evaluate the relative and absolute error. Further comment on the accuracy of the result.

Why the calculations through calculator are approximate?
