:Caution:
::This implementation of error propagation does not address issues of dependent and independent values. It is assumed that a and b are independent and so the formula for multiplication should not be applied to a*a for exam[ple. See [[Talk:Numeric_error_propagation|the talk page]] for some of the implications of this issue.

;Task details:
# Add an uncertain number type to your language that can support addition, subtraction, multiplication, division, and exponentiation between numbers with an associated error term together with 'normal' floating point numbers without an associated error term. <br>Implement enough functionality to perform the following calculations.
