What i think i did well for this chapter?

I think that i have improved on expanding, because last year, i did not understand this chapter very well.In addition, i used to hate algebra.Now that i have under stand tha concept, i can now do better in practices and hopefully in exams.I have also improved in ht e 'changing in signs' for all my workings and from there, i could have a higher chance of getting my answere correct.Overall, I think that i did well for this chapter and i had done my best for everything i do for it.
