WitrynaThroughout the twentieth century there was debate as to the primacy of ordinality or cardinality in the development of the concept of number. Psychological experiments have largely given way to neuro-science in deciding this issue. There are results suggesting students' awareness of symbol-symbol relations is the best predictor of future … WitrynaIn mathematics, transfinite numbers are numbers that are "infinite" in the sense that they are larger than all finite numbers, yet not necessarily absolutely infinite.These include the transfinite cardinals, which are cardinal numbers used to quantify the size of infinite sets, and the transfinite ordinals, which are ordinal numbers used to provide an ordering of …
