1. The first number is positive and the second number is negative, so the sign of the final answer will be negative.

  140 x (-5)

= 140 x 5

= 700            (Now, we add the minus sign)

= (-700)

2. Both the numbers are negative, so the sign of the final answer will be positive.

  (-13) x (-13)

= 13 x 13

= 169            (Now, we add the plus sign)

= 169 or (+169)
