See on mehaaniline kalkulaator nimega \u201c\u0424\u0435\u043b\u0438\u043a\u0441\u201d (Felix)<\/strong>, mida toodeti N\u00f5ukogude Liidus Schetmaschi tehases Kurskis<\/strong>. Tegemist on aritmomeetriga<\/strong>, ehk k\u00e4sitsi juhitava arvutusmasinaga, mis v\u00f5imaldas teha liitmist, lahutamist, korrutamist ja jagamist<\/strong> enne elektrooniliste kalkulaatorite tulekut. <\/p>\n
