I had to learn from going to the specific to the general in learning algebraic concepts.
Example:
I knew/know that some number plus another number equals a third number:
5+ 3 = 9
a + b = c
I went back to our local community college about 15 years ago. I absolutely LOVED going.
I asked if I could attend the "remedial" classes so that when I was tutoring I would use the same terms and methods that my tutees were learning.
I learned (or finally understood!) so much from going to those classes!
