# How do you find the product of 3z-6x?

An answer, assuming $3 z \times 6 x$ was meant

#### Explanation:

I'll answer this assuming the question is meant to be $3 z \times 6 x$

The operation holding the 3 and the $z$ together is multiplication, as is $6 \times x$, and so we can rewrite the question as:

$3 \times z \times 6 \times x$

I can reorder this and not change the value of the multiplication:

$3 \times 6 \times x \times z$

And I can group things together:

$\left(3 \times 6\right) \times x \times z$

$3 \times 6 = 18$, and so:

$18 \times x \times z$

At this point I can't do anything else. Both $x$ and $z$ are unknown values and so we simply leave them alone. Since we can write multiplication simply by having the variables sit next to other variables or constants, I can write the expression as:

$18 x z$
