I just need some help clearing something up, that i don't quite understand:
2/3 x 18c=2/3 x 18 x c
That's Right, right? But how did i get the 2/3 x 18??? How was i mean't to get 12?
This is out of a example page, when were talking about how any two terms can be multiplyed together!
Can you help me clear this up?
