[ 2 ] Similar tests include serial threes where the counting downwards is done by threes, reciting the months of the year in reverse order, or spelling 'world' backwards.
Reverse mathematics is a program in mathematical logic that seeks to determine which axioms are required to prove theorems of mathematics. Its defining method can briefly be described as "going backwards from the theorems to the axioms", in contrast to the ordinary mathematical practice of deriving theorems from axioms.

The Nine Chapters used red counting rods to denote positive coefficients and black rods for negative. [ 4 ] [ 26 ] This system is the exact opposite of contemporary printing of positive and negative numbers in the fields of banking, accounting, and commerce, wherein red numbers denote negative values and black numbers signify positive values.
