Q. Evaluate.

-3 \times(-9)=

Determine Result Sign: Since we're multiplying two negative numbers, the result will be positive. $\newline$ Calculate: $-3 \times -9$
Calculate Multiplication: Do the multiplication ignoring the signs first: $3 \times 9 = 27$
Apply Rule for Negatives: Now remember the rule for multiplying negatives: a negative times a negative gives a positive. $\newline$ So, $-3 \times -9 = +27$
