Your daughter is lucky to have your support.  Most girls with a talent for logical fields like math understand very early that the perennial discussion about women not being "good at math" is the misapplication of a questionable statistic that just creates a barrier for women who are "good at math" to fairly participate, and the result is they choose to move on to other studies instead of banging their head against a wall.

The only way to change the prejudice is for women to do it.  And despite the fact that participation of women in tech is persistently low, the good news is that it is increasing in other fields of engineering.  We will overcome.
