Using the fact multiplication is commutative, a negative times a positive is also negative. Similarly, we can prove that a negative times a negative is a positive. Since we know that −ab is negative, and the sum of these two terms is 0, therefore (−a) × (−b) is positive.
Regarding this, What is the rule for subtracting negative numbers?
Subtracting a negative number is like adding a positive; you move to the right on the number line. Example 4: Subtract −4−(−7) . Start at −4 , and move 7 units to the right.
Beside above, What is a negative divided by a negative?
Like a negative divided by a negative will always be positive.
What is negative multiplied by negative? When you multiply a negative by a negative you get a positive, because the two negative signs are cancelled out.
