Multiply by 3

Step

1. Divide first digit by 2 and remove all digits after point.

2. Minus all digits from 9 but unit digit from 10.

3. We find a new number.

4. Double each digit of new number and add half of next main number’s digit (Ignore Digit after point).

5. Add extra 5 if main digit is odd and 0 if even.

6. Carry forward answer’s digit before unit digit to next digit.

7. Minus 2 from first digit of finding.

E.g. 46357 x 3

Step

1. 4/2 = 2

2. 9 – 4, 9 – 6, 9 – 3, 9 – 5, 10 – 7 = 53643

3. 53643

4. (5 x 2) + 6/2, (3 x 2) + 3/2. (6 x 2) + 5/2, (4 x 2) + 7/2, (3 x 2) + 0/2 = 13, 7, 14, 11, 6

5. 13 + 0, 7 + 0, 14 + 5, 11 + 5, 6 + 5

6. 13, 07, 19, 16, 11 = First digit 2 = 339071

7. Finding 339071 minus 2 from first digit = 1339071

1 | 2 | 3 | 4 | 5 | 6 |

Main Number | Minus 9/10 | Double 2 | Odd/Even | ½ of next digit | 3+4+5 |

0 | 0 | 0 | 0 | 2 | 2 |

4 | 5 | 10 | 0 | 3 | 13 |

6 | 3 | 6 | 0 | 1 | 7 |

3 | 6 | 12 | 5 | 2 | 19 |

5 | 4 | 8 | 5 | 3 | 16 |

7 | 3 | 6 | 5 | 0 | 11 |

339071

Now Minus 2 from first digit 3 – 2 = 1

Answer is 139071

1 | 2 | 3 | 4 | 5 |

Main Number | Minus 9/10 | Odd/Even | ½ of next digit | 2+3+4 |

0 | 0 | 0 | 1 | 1 |

3 | 6 | 5 | 3 | 14 |

7 | 2 | 5 | 2 | 9 |

4 | 5 | 0 | 4 | 9 |

8 | 1 | 0 | 2 | 3 |

5 | 5 | 5 | 0 | 10 |

Now minus 1 from first digit 2 – 1 = 1

Answer is 149940

0 | 0 | 3 | 3 |

7 | 5 | 4 | 9 |

8 | 0 | 2 | 2 |

4 | 0 | 1 | 1 |

3 | 5 | 4 | 9 |

9 | 5 | 0 | 5 |

Now answer is 392195

2. Multiply by 10 and divide by 2.

E.g. 78439 x 5

78439 x 10 = 784390

784390/2 = 392195
