Q. Simplify the expression:

\newline

(-2r)(-2) =

_____

Multiply two numbers: First, we gotta multiply the two numbers together, so we do $(-2r)$ times $(-2)$ . When you multiply two negatives, it's like they cancel out and you get a positive, so it's just $2r$ times $2$ . $\newline$ Calculation: $(-2r)(-2) = 4r$
