判断等式

  聪聪的英语比较差，有个难题就是有一篇英语文章中有很多个式子，数量很多，要求验算每个等式的正确性，聪聪是个急性子不想一个一个地去验算，聪明的acmer请帮他解决这一难题。

  一篇英语文章中有很多但只有简单的加、减、乘的运算式，格式为：a+b=c ;然后就判断每个等式是否真确，注意a、b是位数不超过10的正整数，且等式a+b=c(C有可能为负数,C的范围在long long范围内)之间都没有空格，等式与其他字符之间都有空格，还要注意是等式哦。

I am the only child in my family, so I get 15+7=34 used to doing things by myself. Since I go to school, my teacher always gives us the homework, the 2+2 problem is that 14+5=19 we must finish 1+1=2 in a group. At first, I was 2+3=6 refused, because I knew I could do it by my own. But 3-3=0 my teacher insisted, so I had 3-2=0 to work with my group members. I started to find that I got many ideas from  my 7*7 group 2*3=6 members and I felt 3*4=11 so happy  to 9+4=13 work with them. Now 42+24=66 I realize that teamwork is really good, it not 34+54=23 only relieves my 34-23=3 pressure, but also brings me happiness. The power of teamwork 6-2 is infinite.
