2、1 = 55 1 = 45 4 = 1数字拆分5232 + 3 = 53 + 2 = 55 2 = 35 3 = 2数字拆分6242 + 4 = 64 + 2 = 66 2 = 46 4 = 2数字拆分6333 + 3 = 66 3 = 3数字拆分6151 + 5 = 65 + 1 = 66 1 = 56 5 = 1数字拆分7343 + 4 = 74 + 3 = 77 3 = 47 4 = 3数字拆分7161 + 6 = 76 + 1 = 77 1 = 67 6 = 1数字拆分7252 + 5 = 75 + 2 = 77 2 = 57 5 = 2数字拆分8444 + 4 = 88 4 = 4数

3、字拆分8171 + 7 = 87 + 1 = 88 1 = 78 7 = 1数字拆分8262 + 6 = 86 + 2 = 88 2 = 68 6 = 2数字拆分8353 + 5 = 85 + 3 = 88 3 = 58 5 = 3数字拆分9363 + 6 = 96 + 3 = 99 3 = 69 6 = 3数字拆分9181 + 8 = 98 + 1 = 99 1 = 89 8 = 1数字拆分9272 + 7 = 97 + 2 = 99 2 = 79 7 = 2数字拆分9454 + 5 = 95 + 4 = 99 4 = 59 5 = 410的组合你认识我吧，我是10哦10的组合1 + 9 =

4、 109 + 1 = 1010 - 1 = 910 9 = 11的补数是99的补数是1所谓补数，就是相加等于10的两个数10的组合2 + 8 = 108 + 2 = 1010 - 2 = 810 8 = 22的补数是88的补数是210的组合3 + 7 = 107 + 3 = 1010 - 3 = 710 7 = 33的补数是77的补数是310的组合4 + 6 = 106 + 4 = 1010 - 4 = 610 6 = 44的补数是66的补数是410的组合5 + 5 = 1010 5 = 55的补数是5我们开始学凑十加法9+7 =+凑十加9 + 7 =+16106我是9，再补1就等于10那我分

5、1给你凑十加8+6 =+凑十加8 + 6 =+14104那我分2给你我是8，再补2就等于10凑十加6+5 =+凑十加6 + 5 =+11101那我分4给你我是6，再补4就等于10凑十加7+6 =+凑十加7 + 6 =+13103那我分3给你我是7，再补3就等于10凑十加9+3 =+凑十加9 + 3 =+12102那我分1给你我是9，再补1就等于10小朋友你来算一算：85 =+13小朋友你来算一算：86 =+14小朋友你来算一算：96 =+15小朋友你来算一算：94 =+13小朋友你来算一算：75 =+12小朋友你来算一算：74 =+11小朋友你来算一算：65 =+11破十减16 - 8 =266减8不够减，就用10位来减8，再加上个位数68610-8+破十减15 - 9 =155减9不够减，就用10位来减9，再加上个位数56510-9+破十减17 - 8 =277减8不够减，就用10位来减8，再加上个位数79710-8+破十减11 - 4 =611减4不够减，就用10位来减4，再加上个位数17110-4+破十减13 - 5 =533减5不够减，就用10位来减5，再加上个位数38310-5+破十减14 - 7 =344减7不够减，就用10位来减7，再加上个位数47410-7+小朋友，现在你来练习13
