How can you use the product of 108 and 4 to find the product of 324 x 4?
I suppose we should notice that 324 is 3 times 108
so whatever you get from 108*4 we have multiply be 3 to get 324*4
well, in my head , 108 times 4 is 324, so to get 324 times 4, I guess
we could multiply 108 times 12 ??
Don't know what the point of this problem is, geeesh, just multiply 324 by 4, that can be done mentally.
