①の式の意味がわかりません教えてください。

A 割り算 次の問題について,考えてみよう。 問題 私の年齢を3で割った余りは2,5で割った余りは 3,7で割った 余りは4である。私の年齢は何歳か。 ただし, 105歳より下である。 練習 16 104 以下の自然数について,次の問いに答えよ。 (1) 7で割った余りが4になる自然数を,次のように書き出せ。 4 11 18 (2)(1) の自然数を5で割ったときの余りをその数の下に書け。 (3)(2) で余りが3になった自然数について, 3で割った余りを更にそ の下に書き,余りが2になる自然数を見つけよ。 練習 16 から,上の問題の私の年齢がわかる。 また、次のような計算 方法もある。 3, 57で割った余りがそれぞれα, b, c であるとき, 70α+216+15c ① を計算する。そして、①から357 の最小公倍数である 105 を引い て残りを求める。残りが105 以上であればまた 105 を引くことを繰り返 す。 最後の残りが答えである。 いい換えると, ① を 105 で割った余り が答えである。 ...... 70a+216+15c=70・2+21・3+15・4=263 263-105=158,158-105=53 ←263 を 105 で割る と余りは 53 この結果から,私の年齢は53歳であるとわかる。 ひゃくごげんざん じんこうき この方法は百五減算と呼ばれるもので, 江戸時代の数学書『塵劫記』 に同様な問題と解答が記されている。
