Practice makes perfect

To evaluate the given expression for a = -6 and b = -4, first, we should substitute these values into the expression.

-2a+b

a= -6, b= -4

-2( -6)+( -4)

When multiplying real numbers, the product will be positive if the signs are the same and it will be negative if the signs are different. cc Same Sign & Different Signs (+)(+)=(+) & (+)(-)=(-) (-)(-)=(+) & (-)(+)=(-) In our case both numbers are negative, so the product will be positive.
