We developed a method of generation and recognition of numerals, included a 3-level general model of numerals and algorithms of interacting models and numerals, allowing transform between numerals and numbers and translate numerals. We used formal grammatics and Markov's normal algorithms. We also developed a Markov's normal algorithm modification for creating more effective algorithms by complexity of decision.
