There is a multiplication formula obtained by multiplying two three-digit numbers: \overline{AAA}*\overline{BBB}=\overline{CDEFGB}, where A≠B, B, C, D, E, F, G these 6 The letters represent exactly (1/7) the 6 numbers in the cycle section after being converted into decimals (the order is not necessarily the same). A+B=how much.
有两个三位数相乘所得的乘法算式：\overline{AAA}*\overline{BBB}=\overline{CDEFGB}，其中，A≠B，B，C，D，E，F，G这6个字母恰好代表(1/7)化成小数后循环节中的6个数字(顺序不一定相同)．A+B=多少．
