To solve the multiplication problem \(-3(6)\), we need to multiply the two numbers together. The multiplication of a negative number and a positive number results in a negative number. Therefore, the product of \(-3\) and \(6\) will be negative.
Step 1: Identify the Expression
We start with the expression to be evaluated:
\[
-3(6)
\]
Step 2: Perform the Multiplication
Next, we multiply the numbers:
\[
-3 \times 6 = -18
\]
Final Answer
The result of the multiplication is
\[
\boxed{-18}
\]
