The Irish writer Lewis once wrote an ironic fable, which described a barbaric country called Niatebo. The West Baba numerals are used in this country. The shape of the West Baba numerals is the same as the general Arabic numerals, but the meaning is reversed. For example, "0" means "9", "1" means "8", and so on. They write numbers from left to right, using the same arithmetic symbols as we use. For example, they use 62 to represent the 37 we wrote. According to the custom of Natebo people, how should the sum of 837+742 be written?
爱尔兰作家刘易斯曾写过一篇反讽寓言，文中描述了一个名为尼亚特泊的野蛮国家．在这个国家里使用西巴巴数字．西巴巴数字的形状与通用的阿拉伯数字相同，但含义相反．如"0"表示"9"，"1"表示"8"，以次类推．他们写数字是从左到右，使用的运算符号也与我们使用的一样．例如，他们用62代表我们所写的37．按照尼亚特泊人的习惯，应怎样写837+742的和是多少．
