Answer and Step-by-step explanation:
Assuming that both values of a and b are positive, we get the result to be positive, so a + sign (though you don't have to put that in front of the value).
When you multiply 2 positive values, the result is always positive.
Multiplying a positive and a negative value results in a negative value.
Multiplying 2 negative values together results in a positive value.
