I was terrible, terrible at math as a high school student.
I didn't know why.
I was a fixed mindset on math too. I had a very smart honors-student friend and I believed he was just born knowing math. That fixed mindset was bad for me learning.

I went to college and took an algebra class.
I really wanted to get past the issues I had in high school.
I decided to do every odd problem at the end of each chapter.
I started thinking deeply about math just so I could hack my way into understanding math.
Then something happened.

I discovered that if you learned the rules of math and just applied those rules you could take on basically any math. You just simply memorize the rules because math is all made up by humans and someone down the line made up the rules for how things work -- for how we calculate.

So, for example I started really looking at the simplest rules:
Commutative property of addition:
1+2 = 2 + 1

No matter the order you add numbers, you get the same answer.

Associative property of addition:
(2+3) + 4 = 2 + (3+4)

Now the student has a base of understanding from simple principles.
Next, explain how the commutative property doesn't work on subtraction

3 - 2 != 2 - 3

Allow them to see that this is just a made-up way of dealing with numbers but it works out.
It's not some huge subject that only geniuses can learn but learning these little things provide confidence.

Next, the = property really helped me understand algebra.
I had to really think about what it meant that two sides of = have to be the same.

5 = 5
5 = 7 - 2
7 - 2 = 5

So then if you do something to one side you have to do something to the other side to keep the = sign true.

step 1. 7 = 7
step 2. 7(+2) = 7
Step 3. what do you need to do to the 7 on the right to get it to be equal?

Later all of this helped me when we got to exponents for example

I was like why can you just add exponents when multiplying exponents ?
for example x^2 * x^4 = x^6
But, why?

Well, because if I multiply out x*x * (x*x*x*x) that would be the same as X^6.
So now I knew the rule and knew "ok, just add up the exponents when you multiply them".
But what about if someone gives you this?
x^2 + x^4
Well, you have to remember that is:
(x*x) + (x*x*x*x) which is 2x + 4x = 6x and 6x is different than x^6.
Now replace using a simple number:
(2*2) + (2*2*2*2)
4 + 16 = 32

(2*2) * (2*2*2*2)
4 * (16) = 64

This was a lot, but I had to see these rules to really get them into my head.

It's a first principle to learn the very basic in a solid way to provide the student with confidence and then from that confidence they can learn and grow much faster.

Build from simple rules.
Good luck.
