I am having an extremely tough time with integers in algebra when simplifying algebraic expressions. No matter which method I use I still end up confused and end up with a completely different answer.
Ex:
5t{7t[4r3(t7)]+6r}4r

PsyDAG,
Please only post your questions once. Repeating posts will not get a quicker response. In addition, it wastes our time looking over reposts that have already been answered in another post. Thank you.
