Starting from (-1) * 5 write various products showing some pattern to show (-1) * (-1) = 1​

Answer 1

Starting from (-1) * 5 write various products showing some pattern to show (-1) * (-1) = 1

According to the pattern,

(−1)×(5)=−5

(−1)×(4)=−4

(−1)×(3)=−3

(−1)×(2)=−2

(−1)×(1)=−1

(−1)×(0)=0

(−1)×(−1)=1

Answer 2

According to the pattern,

(−1)×(5)=−5

(−1)×(4)=−4

(−1)×(3)=−3

(−1)×(2)=−2

(−1)×(1)=−1

(−1)×(0)=0
