The ways to express multiplication
X: Cross aXb means a times b
. dot 3.a means three times a or 3 a
No sign : implied multiplication (3a+5)(2b-7)=(3a+5)X(2b-7)
Repeated multiplication aXaXaXa= a^4. This is read a to the 4th power, or a exponent 4.
More Multiplications
With vectors you have two other types of multiplication.
Scalar product (also called dot product) vect(a).vect(b)
Vector product; vec(a)Xvec(b)
You have multiplication of complex numbers, and multiplications of matrices, multiplication of tensors.

### Factors of -14abc/12ac

That is not factoring you need but simplifying.
First you deal with the numerical numbers -14/12=-7/6
Then consider the letters a/a=1
c/c=1
Thus (-14abc/12ac)=(-7/6)(a/a)b(c/c)=(-7/6)(1)(b)(1)=-7b/6
If you have a product each symbol separated by a multiplication sign from another symbol is called a factor. Remember that the multiplication sign is not always shown.

### Can't find the \$ symbol on the 7410 officeject

I looked through the manual and on page 112 it lists the characters available. It seems the \$ symbol isn't available, so you can't enter it. You can download a copy from HP here if you've misplaced your copy. The manual makes mention of an on-screen keyboard you can pick from. Maybe the symbol is there. I don't have one of these, so I can't check it for myself.
