A person skilled in arithmetic or mathematics, especially someone who specializes in numerical calculations and mathematical reasoning.
From Greek 'arithmetike' (arithmetic) + '-ian' (person skilled in). This term was more common in older texts for mathematicians and numerical specialists.
An 'arithmetician' sounds like an ancient wizard with mystical powers over numbers—but it's just an old-fashioned word for 'someone really good at math'!
The -cian suffix historically defaulted to masculine form; women mathematicians were often excluded from formal titles and recognition until the 20th century.
Use 'mathematician' or 'arithmetic specialist' for gender neutrality; if historical specificity needed, 'arithmetician' applies to any gender.
["mathematician","arithmetic specialist","numeracy expert"]
Women contributed foundationally to mathematics (Hypatia, Émilie du Châtelet, Sophie Germain) but were systematically denied the title 'arithmetician'—reclaim it as non-gendered.
