Question Answer Steps of Solution
找出空格里的加数 18452 + {43829} + 27619 = 89900 89900 – 18452 – 27619 = 43829
找出空格里的加数 21567 + {35016} + 19873 = 76456 76456 – 21567 – 19873 = 35016
找出空格里的加数 19384 + {37420} + 14296 = 71100 71100 – 19384 – 14296 = 37420
找出空格里的加数 27619 + {25138} + 34012 = 86769 86769 – 27619 – 34012 = 25138
找出空格里的加数 14567 + {42731} + 21852 = 79150 79150 – 14567 – 21852 = 42731
找出空格里的加数 23456 + {29874} + 14321 = 67651 67651 – 23456 – 14321 = 29874
找出空格里的加数 17892 + {31607} + 28701 = 78200 78200 – 17892 – 28701 = 31607
找出空格里的加数 20234 + {25165} + 30760 = 76159 76159 – 20234 – 30760 = 25165
找出空格里的加数 28674 + {16821} + 28795 = 74290 74290 – 28674 – 28795 = 16821
找出空格里的加数 13457 + {39862} + 26718 = 80037 80037 – 13457 – 26718 = 39862
