Tujuan dari penelitian ini mendeskripsikan aktifitas menghitung dan mendeskripsikan perhitungan yang dilakukan oleh masyarakat jawa berbantuan software microsoft excel dan microsoft mathematics. Jenis penelitian ini adalah deskriptif kualitatif dengan menggunakan pendekatan etnografi. Permasalahan yang diteliti adalah berkaitan dengan sistem perhitungan yang digunakan oleh masyarakat jawa yang diperoleh melalui kegiatan eksplorasi dan observasi yang kemudian menjadi bahan pengembangan peneliti untuk melakukan studi literatur untuk menentukan keterkaitan sistem perhitungan jawa dengan sistem bilangan basis serta pemanfaatan software untuk mempercepat proses perhitungannya. Beberapa tradisi yang berkaitan dengan aktifitas berhitung adalah perayaan 5 hari dan 35 hari kelahiran bayi, peringatan 7 hari, 40 hari, 100 hari, dan 1000 hari meninggalnya seseorang. Perhitungan penentuan waktu peringatan kelahiran dan kematian itu menggunakan rumus sederhana yaitu ?nortu sartu?, ?nomosarmo?, ?norosarmo?, ?nonemsarmo?, dll yang melibatkan pasaran yaitu Pon, Wage, Kliwon, Legi dan Pahing, melibatkan 7 hari, serta melibatkan nama Wuku. Dipandang dari perspektif matematika, perhitungan jawa menerapkan proses konversi bilangan dari basis yang satu ke basis lainnya. Dengan menggunakan bantuan sofware matematika seperti microsoft excel dan microsoft mathematics konversi basis bilangan dapat dilakukan sehingga dapat dengan mudah menentukan hari, pasaran, dan wuku atas perayaan peringatan kematian dan kelahiran. Microsoft excel menyediakan proses konversi bilangan dengan cepat untuk basis bilangan khusus yakni biner, oktal, dan heksadesimal. Sedangkan software microsoft mathematics menyediakan proses konversi yang berulang untuk semua bilangan basis 2 hingga basis 36.

Mathematical communication is a crucial 21st-century skill related to achievement and other skills. This study aims to analyze the differences in mathematical communication abilities and describe the difficulties male preservice teachers (MPT) and female preservice teachers (FPT) face in solving gender-biased Higher-Order Thinking Skills (HOTS) problems. This research employs a sequential explanatory mixed-methods design. The respondents, selected through purposive sampling, consisted of 4 MPTs and 10 FPTs. Data on mathematical communication abilities were obtained through a gender-biased HOTS problem-solving test. The respondents' difficulties in solving the problems were gathered through interviews. The results indicate differences between MPT and FPT mathematical communication skills using symbols and mathematical notation in solving problems. Student's difficulties in solving gender-biased HOTS problems are unfamiliarity and disinterest in the context. This study implies that education should emphasize contextual understanding and utilize gender-neutral problems to enhance mathematical communication skills.
