This statement is true. As positive multiplied by a positive gives a positive, for example 4×5=20. Similarly, a negative multiplied by a negative gives a positive, for example -4×-5=20. However, if an odd number of negatives are being multiplied together, then the product will be negative, for example -4×-5×-1= -20. But it an even number of negatives are being multiplied together, then the answer will be positive.
