A sense of pride flooded my mind. I believe that if everyone has a natural interest in mathematics and especially likes learning mathematics, I believe that this person has gone through hardships and finally successfully solved a particularly complicated math problem. Later, he also had pride, pride from the heart, pride from the heart. This is our affirmation of our own strength and a sense of pride. This kind of emotion is sincere.
Joy and pride arise spontaneously. Of course, joy and pride are the same. Why do you say that joy and pride are innate? That's because when we encounter this difficult and complicated math problem, we feel that we can't get through it, just like we are in the darkest valley of our lives. I was really desperate at that time. You finally broke through the difficulties through your own efforts, and you will feel happy and proud after solving the difficulties.
Generally speaking, the idea in my mind is that I solved this set of difficult math problems, and then I feel proud and happy, because I broke through a math problem that no one else can solve, and as a person who loves math very much, after solving a particularly complicated math problem, my pride and pride suddenly came out, which is normal, so I only have joy and pride in my heart.
