Question

Which statement does NOT follow the rules for multiplying integers?

A) If both a and b are positive integers, then a x b = ab.
B) If both a and b are negative integers, then a x b = ab.
C) If both a and b are negative integers, then −a x −b = −ab.
D) If a is a negative integer and b is a positive integer, then −a x b = ab.

Answer 1

If both a and b are negative integers, then −a x −b = −ab.

If both are positive: (+)(+) = + (TRUE)

If both are negative: (−)(−) = + (TRUE)

If a is negative and b is positive: −a is positive and b is positive;

(+)(+) = +. (TRUE)

If a is negative and b is negative:

−a and −b are both positive: (+)(+) = +; therefore the statement "If both a and b are negative integers, then −a x −b = −ab" does NOT follow the rules for multiplying integers.

Answer 2

c the answer is c cause 2 negatives = a positive
