Question

how do you find the answer to 2(-4)

Answer 1

Given the general rule for multiplication with signs:

$\begin{gathered} (-)(-)=+ \\ (-)(\text{ + )=-} \\ (\text{ +)(-)=-} \\ (\text{ +)( +)=+} \end{gathered}$

in this case, we have the following:

$(2)(-4)=-8$

notice that we used the third case of the rule of the signs. Therefore, the answer is -8
