Use addition:

765 + 98:

Line up our numbers vertically:

7 | 6 | 5 | |

^{+} | 9 | 8 |

7 | 6 | 5 | |

^{+} | 9 | 8 | |

3 |

Column 1: 5 + 8 = 13

Since 13 > 9, we take the right digit = 3.

Carry the 1 for Column 2

^{1} | |||

7 | 6 | 5 | |

^{+} | 9 | 8 | |

6 | 3 |

Column 2: Carry the 1 from Column 1

1 + 6 + 9 = 16

Since 16 > 9, we take the right digit = 6.

Carry the 1 for Column 3

^{1} | ^{1} | ||

7 | 6 | 5 | |

^{+} | 9 | 8 | |

8 | 6 | 3 |

Column 3: Carry the 1 from Column 2

1 + 7 + 0 = 8
