If the ^ is a multiplication symbol, and you mean "expand" by using the distributive property, then this is the answer.
n(a+b+c) is the same as:
n(a) + n(b) + n(c)
Which is na+nb+nc
Hopefully, you know what this distributive property is, That would be VERY VERY helpful. I'll try to explain:
If you said 6(5-3), according to PEMDAS, you do the parenthesis first.
6(5-3)
6(2)
12
Okay? But, according to the distributive property, you can say that:
6(5-3) = 6(5) - 6(3)
So,
6(5) - 6(3)
30 - 18
12
See? Whether you use PEMDAS or the distributive property, you get the same answer.
