Waliwo akakwaate akatasattululwa wakati w‘obwakalimagezi n’ebirowoozo ebisengeke (logic). Mu butuufu “ekipimo ky’obwakalimagezi” (EkyO) kisinziira ku ngeri omuntu gy’alaga obusobozi bw’alina okusengeka ebirowoozo bye nga alambulula oba ng’alambika ensonga ez’enjawulo. Ssessomo ly’ekibalangulo (mathematics discipline) liyamba nnyo okukulaakulanya obusobozi bw’okusengeka ebirowoozo. Omuntu atalina busobozi bwa kusengeka na kukwataganya birowoozo tasobola kubeera mubalanguzi (mathematician).
