Problem Description
读入两个小于100的正整数A和B,计算A+B.
需要注意的是:A和B的每一位数字由对应的英文单词给出.
 

Input
测试输入包含若干测试用例,每个测试用例占一行,格式为"A + B =",相邻两字符串有一个空格间隔.当A和B同时为0时输入结束,相应的结果不要输出.
 

Output
对每个测试用例输出1行,即A+B的值.
 

Sample Input
one + two =
three four + five six =
zero seven + eight nine =
zero + zero =
 

Sample Output
3
90
96
