AITA for exploding at my family because my 7th grade son thinks dad is slightly better at math? NTA sweaty women in stem!

The math teacher asked the class (7th grade) if their parents can still help or if they slowly reach their limits. My son told in class that his father has no problems at all but I start struggling. When he told me that I felt really hurt. My husband stepped in, I thought he would have my back bc first he said that this wasn't true. Then my son clarified that the question was only about maths….then my husband smiled and said „well, then that's fine“ and lightly laughed. I totally lost it. For some background: I hold a university degree in psychology, math is also a part of my education (statistics, probability calculation) but I'm not really interested in maths but really like learning and teaching my son about languages and biology. So I help my son with German, English, French and Latin as well as biology, music and random other school topics. So when it comes to maths and physics I stepp back and my husband takes over. My thoughts are „why should I put effort in a topic I don't really appreciate when my husband - a studied physicist- can do it faster“. They both interpreted this as „she's at her limit, haha“. AITA for reacting very emotionally and starting a fight?

EDIT: some of you asked for more clarification (very much appreciated instead of judging at first glance).

I used some expressions incorrectly , I am not a native speaker. We had a heated discussion for about 5 minutes where I criticized his attitude. I asked for 5 minutes alone time, then we apologized to each other.

Before the discussion with my HUSBAND I very calmly explained to my nearly 14 year old son, that I feel he gave a wrong presentation of me to his teacher in front of the class. I reacted emotionally when my husband laughed at me.Z

I do at least 90% of all school support (that's expected here in our school system, they lack a lot of professional teachers) including maths! When the new topic was introduced my husband showed more interest than before. That's when I took the chance to step back a little.

It‚s not about maths anyway. It was my husband's behavior, the laughing, the attitude. He doesn't like driving the car, no one would assume he is not capable. There have been comments in the past from people, I always stepped in and said I like it more so he lets me. He didn't pay back.

NTA.

My sister is amazing at math. She has a master's degree and a career in math. But when she was in 8th grade, she had a male math teacher who told her that she shouldn't expect to have a career in math because she is a girl and she is just naturally not as good at math as the boys. There's a lot of sexism in math.

I get why you were upset. As a woman in science, I bet you've had similar experiences. I know I have.

Women have to fight extra pressure to prove they are good at math because of sexism. It would break my heart if I found out my sons thought I couldn't do 7th grade math. I'm sue it broke yours too.

The A's here are your husband for laughing and all the men who tried to teach you that you shouldn't expect to be good at math.
