Math is something you are either inherently good or bad at - Society conditions many people to approach math with a fixed mindset, the idea that you are either good at it or bad at it and nothing you do can change that.
Truth - Mathematical ability is like any other skill. If you approach it with a growth mindset, you can improve!
When the math gets tough it's a sign that you're doing it "wrong". - Every time you are learning a new concept maths will be easier for everyone or if they just come with the right mindset.
Truth - Learning something new, learning to think in new ways, can be challenging! Learning to work through and overcome that challenge is itself a valuable skill.
Mathematics is following all boring memorization and formulaic procedures - Memorization has a place in math. Algebra is much easier if you can see a number like 56 and quickly recognize its factors (8 times 7).
Truth - There are also formulas that come up often enough that it is helpful to memorize them, and you might be able to pass an algebra class by memorizing specific processes.
Being good at math means being able to solve the questions as fast as possible - Admittedly, sometimes getting a good grade in a particular math class or a good score on a particular test can rely on how quickly you can do the problems.
Truth - Succeeding at higher levels of math relies on persistence, creativity, and a willingness to engage with abstract ideas, not speed.
