With regard to symbolism, Hairwoman stated, "Once you figure it out, it's clear as day". How does this relate to Melinda in Speak?

Melinda calls her English teacher Hairwoman. In class, they are studying The Scarlet Letter by Nathaniel Hawthorne. Hairwoman calls Hawthorne a literary genius and tries to get her students to understand the symbolism in his text. Melinda's former friend Rachel (who now goes by Rachelle) speaks up and questions whether the symbols Hairwoman is discussing are truly intentions from the author or not. This prompts Hairwoman to say:

“Do you tell your math teacher you don't believe that three times four equals twelve? Well, Hawthorne's symbolism is just like multiplication—once you figure it out, it's as clear as day.”

Hairwoman then assigns an essay on symbolism and hidden meanings, so the other students yell at Rachel/Rachelle after class. Melinda observes:

That's what you get for speaking up.

To Melinda, it is currently "clear" that she can't say anything about her experience. To us, Hairwoman's quote is a hint to look for the hidden meaning in this chapter. Melinda talks about how looking for the symbols can be fun:

Some of it is fun. It's like a code, breaking into his head and finding the key to his secrets.

Once we break the code and figure out Melinda's secret, it is "clear as day." Melinda identifies with Hester because she has been raped and feels ostracized by those around her.
