Looking for examples of alt text for math equations

When I write alt text for equations, I keep it as natural as possible, like I’m reading it out loud to a real person. For something simple like x² + 5 = 12, I’d just say “x squared plus five equals twelve.” But if it’s more complex, like a fraction or something with brackets, I spell out the structure, like “the quantity x plus one divided by the quantity x minus one.” I don’t overcomplicate it, I just focus on making it clear when spoken.
