Today after the elementary schools day had ended, my mom and I were in her 1st grade classroom. While we were grading some of students subtraction papers my mom burst out laughing. It turns out that one of the little girls in the class didnt feel like doing subtraction that day and had changed all of the minus signs into addition. She from there managed to add all of the numbers correctly with the exception of one problem. My mom gave her full credit. You are my hero little girl. MLIA
