Question 12
(−11)×7 is not equal to
(a) 11×(−7)
(b) −(11×7)
(c) (−11)×(−7)
(d) 7×(−11)
(−11)×7=(−77)
(we know, in multiplication, if the sign of both numbers are different, then the sign of the resultant is negative and if the sign of both numbers are same, then the sign of the resultant is positive.)
(−11)×(−7)=77
