ターミナル立ち上げてすぐに数式を入力できる

数値計算・代数計算にとって強力な助っ人SymPyをもっと簡単に
Pythonは素晴らしい言語です
SymPyライブラリは数学の強力助っ人

でも使うためにはいくつものお膳立てが必要

ターミナルにコマンドpcを打ち込むだけでPython一行コードを即入力・即出力を可能にします

Pythonを立ち上げる必要なし
Pythonのコーディングも必要なし
SymPyライブラリのインポートはじめお膳立ても必要なし
シェルスクリプトは1つpc.shだけだから設置が容易

3ステップで高度な数学計算ができる
1.ターミナルを立ち上げる
2.コマンドpcを打ち込む
3.数式 expand((x+y+z)**3)を入力
