I can use the distributive law to multiply an expression by a term.
I can use the distributive law to multiply an expression by a term.
Constant - A constant is a term that does not change; it contains no variables.
Variable - A variable is a quantity that can take on a range of values.
How to deal with exponents. y^2 times by y makes 3y. Or at least has a coefficient that is not 1.
Unsimplifying first. Not sure? Break it down. What is it? a^2 is a x a. So a^2 x a must be a x a x a.

$$x+x$$ -Â $$2x$$
$$x \times x$$ -Â $$x^2$$
$$x \times y$$ -Â $$xy$$
$$y \times y$$ -Â $$y^2$$
$$y+y$$ -Â $$2y$$
$$2(x+5)$$ -Â $$2x+10$$
$$2(x-5)$$ -Â $$2x-10$$
$$-2(x-5)$$ -Â $$10-2x$$
$$-2(x+5)$$ -Â $$-2x-10$$
