Question

multiply: 7 × -7 = \boxed{}

Explanation:

Step1: Recall multiplication rule for signs

When multiplying a positive number and a negative number, the result is negative. Also, \(7\times7 = 49\).

Step2: Apply the rule to \(7\times(-7)\)

Since one number is positive (\(7\)) and the other is negative (\(-7\)), the product will be negative, and the magnitude is \(7\times7 = 49\). So \(7\times(-7)=- 49\).

Answer:

\(-49\)
