定期的に暗算を練習できるソフトウェアはありますか？

Question

私は怠け者の性質を認識しており、時々基本的な暗算を行うように努力する必要があります。したがって、私は定期的に短い暗算演算（プラス、マイナス、乗算、除算）を行うように要求するソフトウェアを探しています。

基準：

• インターバル時間をカスタマイズできるようにする必要があります
• Ubuntuデスクトップに統合する必要があります。つまり、バックグラウンドで非表示にし、運動中にのみ表示（ポップアップ）します。

Answer 1

1.簡単なバージョン

以下のスクリプトは、ランダムに割り当てを生成します+、-、×および÷。スクリプトが使用できる最大数、および割り当て間の時間間隔を設定できます（設定する必要があります）。

課題

割り当ては、Zenity入力ウィンドウに表示されます。

答えが間違っている場合：

答えが正しい場合：

スクリプト

#!/usr/bin/env python3
from random import randint
import sys
import subprocess
import time

# maximum number & interval
max_n = int(sys.argv[1]); pause = int(sys.argv[2])

def fix_float(n):
    """
    if the assignment is a division, the script divides the random number by a
    number (integer) it can be divided by. it looks up those numbers, and picks
    one of them (at random). if the number is a prime number the assignment is
    changed into another type
    """
    try:
        divs = [i for i in range(2, n) if n%i == 0]
        pick = randint(1, len(divs))
        div_by = divs[pick-1]
        return [str(n)+" : "+str(div_by), int(n/div_by)]
    except (ValueError, IndexError):
        pass

def get_assignment():
    """
    get a random number within the user defined range, make the assignment and
    the textual presentation
    """
    n1 = randint(2, max_n); n2 = randint(2, max_n)
    assignments = [
        [str(n1)+" + "+str(n2), n1+n2],
        [str(n1)+" - "+str(n2), n1-n2],
        [str(n1)+" x "+str(n2), n1*n2],
        fix_float(n1),
        ]
    # pick an assignment (type) at random
    assignment = assignments[randint(0, 3)]
    # if the random number is a prime number and the assignment a division...
    assignment = assignment if assignment != None else assignments[1]
    # run the interface job
    try:
        answer = int(subprocess.check_output(["/bin/bash", "-c",
            'zenity --entry --title="Think hard:" --text='+'"'+assignment[0]+'"'
            ]).decode("utf-8"))
        if answer == assignment[1]:
            subprocess.Popen(["notify-send", "Coolcool"])
        else:
            subprocess.Popen([

    except (subprocess.CalledProcessError, ValueError):
        pass

while True:
    time.sleep(pause)
    get_assignment()

使い方

1. スクリプトを空のファイルにコピーし、mindpractice.pyとして保存します

2. 最大許容数と、引数間の割り当て間の間隔時間（秒単位）で実行します。

   python3 /path/to/mindpractice.py <max_number> <interval>
   

   例えば.

   python3 /path/to/mindpractice.py 1000 300
   

   1000の数字までの計算を行い、割り当て間を5分間中断します。

3. すべてが正常に機能する場合は、通常の方法でスタートアップアプリケーションに追加できます。or切り替え用のランチャーを作成できます。これは後で追加できます:)

注意

• dividingには説明が必要な場合があります。あなたはおそらくフロートで計算したくないでしょう。したがって、割り当てが除算の場合、スクリプトは除算可能な数値を検索し、1つをランダムに選択します。 （メイン）番号が素数であることが判明した場合、割り当ては別のタイプに変更されます。

---

2.その他のオプション

計算を開始すると、dividing最大で100の数字（たとえば）100は、multiplyingで最大100の数字よりもはるかに簡単であることがわかります。

以下のスクリプトを使用すると、最大数を設定することができます（また、そうする必要があります）運動の種類ごと（スクリプトの下の指示を参照）。

スクリプト

#!/usr/bin/env python3
from random import randint
import sys

    """

    changed into another type
    """
    try:
        divs = [i for i in range(2, n) if n%i == 0]
        pick = randint(1, len(divs))
        div_by = divs[pick-1]
        return [str(n)+" : "+str(div_by), int(n/div_by)]
    except (ValueError, IndexError):
        pass

def get_assignment():
    """

    the textual presentation
    """
    # pick an assignment (type) at random

    n1 = randint(2, max_n); n2 = randint(2, max_n)
    assignments = [
        [str(n1)+" + "+str(n2), n1+n2],

        fix_float(n1),
        ]
    assignment = assignments[track]     
    # if the random number is a prime number and the assignment a division...
    assignment = assignment if assignment != None else assignments[1]
    # run the interface job
    try:
        answer = int(subprocess.check_output(["/bin/bash", "-c",
            'zenity --entry --title="Think hard:" --text='+'"'+assignment[0]+'"'
            ]).decode("utf-8"))
        if answer == assignment[1]:
            subprocess.Popen(["notify-send", "Coolcool"])
        else:
            subprocess.Popen([
                "notify-send", "Oooops, "+assignment[0]+\
                " = "+str(assignment[1])])
    except (subprocess.CalledProcessError, ValueError):
        pass

while True:
    time.sleep(pause)
    get_assignment()

使い方

• 最初のスクリプトとまったく同じようにスクリプトをセットアップしますが、引数を指定して実行します（任意の順序で、スクリプトは正しい引数を正しい項目にリンクします）。

  • p: pause（秒単位の割り当て間のブレーク））
  • s:減算（計算する最大数）
  • a: add（最大数）
  • m:乗算（最大数）
  • d:分割（最大数）

  例えば：

  python3 '/home/jacob/Desktop/num.py' a:10 d:100 s:10 m:10 p:300
  

  5分ごとにエクササイズを表示するには、最大10の数字except図100まで分割します。

---

3.少し夢中になりましょう

いくつかの統計を見ることができる

以下のバージョンは、10回の演習ごとに統計を表示します。

追加（子供用に使用すると役立つ場合があります）、最後の100の誤って回答された演習で何がうまくいかなかったかを確認できます。隠しファイルには、割り当てとその（誤った）回答の両方が書き込まれます。

使い方

使用方法はオプション2とほとんど同じですが、10回の割り当てごとにログファイルとスコアを使用できます。

4.究極のバージョン

以下のバージョンはオプション3（ログファイルとレポートを含む）に似ていますが、いくつかの追加機能があります。

• 計算平方根を追加します

  

• 単純に最大値を設定する代わりに、rangeの数を使用して追加します

• specific計算タイプのみを実行するオプションを追加します（例：除算と乗算のみ）。

• 引数なしで実行された場合、前回実行された引数を記憶します（初回のみ、引数mustが設定されます）。最初の実行時に引数が設定されていない場合、スクリプトはメッセージを送信します。

Use this script to practice head count. Some explanation might be needed:
The script can be used for the following types of calculating:

Type          argument example      explanation
-------------------------------------------------------------------------------
add           a:30-100              to add in numbers from 30-100
subtract      s:10-100              to subtract in numbers from 10-100
multiply      m:10-20               to multiply in numbers from 10-20
divide        d:200-400             to divide in numbers from 200-400
square root   r:1-1000              to find square root in numbers from 1-1000

N.B.
-------------------------------------------------------------------------------
- The argument p: (pause in seconds; break between the assignments) *must* be
  set, for example: p:300 to launch an assignment every 5 minutes
- A calculation type will only run *if* the argument is set for the
  corresponding type. An example: python3 /path/to/script p:60 s:30-60
  will run a subtract- assignment every minute.

Miscellaneous information:
-------------------------------------------------------------------------------
- On first run, arguments *must* be set. After first run, when no arguments
  are used the last set arguments will run, until the script is run with a new
  set of arguments.
- A log file of the last 100 incorrectly answered questions is kept in
  ~/.calculog
- After 10 assignments, the score of the last 10 pops up.

  r:1-1000             to find square root in numbers from 1-1000
  

• コマンド例：

  python3 '/path/to/mindpractice.py' p:300 d:10-100 s:10-30  r:300-600
  

  設定する：

  p:300                to set the interval between assignments to 5 minutes
  d:10-100             to divide in numbers from 10-100
  s:10-30              to subtract in numbers from 10-30
  r:300-600            to calculate square roots from 300-600
