Common meadows are enlargements of a field with an error value and a division function which is made total by setting 1/0 equal to said error value. We discuss properties and axiomatisations of common meadows, and of signed common meadows.

Moreover, we discuss signed infinite values which deviate from the infinite value of Anderson’s transrationals so that fracterm flattening is preserved. Using a modified quotient construction a transformation to a different enlargement of signed common meadows with infinite values.
