Kamu bisa mengurai perkalian sulit! 7 × 6 = 7 × 5 + 7 × 1 = 35 + 7 = 42. Pecah jadi potongan lebih mudah!
Sifat distributif diperkenalkan secara intuitif di sini: a × (b+c) = a×b + a×c. Di SD kita bilang: 'Pecah dan hitung bagian-bagiannya.' Mulai dengan penguraian melalui 5: 7×6 = 7×5 + 7×1. Anak tahu tabel perkalian 5 dan menambahkan sisanya. Penguraian melalui 10 terutama berguna: 9×7 = 10×7 − 1×7 = 70 − 7 = 63.
