I’m Israle and i’m a student going to st jhon coummity collage. I took pre algebra 5 years ago as a freashman in high school. This is my frist year of collage. I have a high school diopoma but these people put me into these prep classes. Per algebra is pretty easy but i do need help sometime. Commutative property of addition, additive identity, additive inverse, distributive property, associative multiplilation, multiplicative identity and closure. I may past the test before you can give this back to me. I mean i past the self test with 100% but the post test i get a 60%. I want to know what going on. If i need more help in math i’ll come back to you.
