Interval Arithmetice Arithmetic operations may be defined on intervals. The operations are expected to return arn interval that contains the image of the input intervals under the operation. Below are some operations and functions that can be applied to interval arithmetic: Addition: a, b]+[e, d la+c,b+d Subtraction: la, b]-[c, d-la-db-cl Multiplication: a, b] c,d-[minlac, ad, bc bd, max(ac, ad, bc bd Reciprocal: Exponent: 1/[a, b] = [1/b, lla] only iro not in [ab]. Power: If n is odd natural number, then [a, b-la, . If n is even natural number, then a",b a 20 b
