1) If the two numbers have different sign like positive and negative then subtract the two numbers and give the sign of the bigger number.
2) If the two numbers have same sign i.e. either positive or negative signs then add the two numbers and give the common sign.
3) (positive) x (positive) = positive sign of the product.
4) (negative) x (negative) = negative sign of the product.
5) (positive) x (negative) = negative sign of the product.
number is positive hence the sign of the product is positive
6) (negative) x (positive) = sign of the product is negative. Note: the answer of the addition or subtraction between two numbers will have the sign of the greater number.
