you must take the sign of the bigger number
negative
If you're talking about multiplication or division, then opposite signs will result in a negative number.
The four possible combinations are:A = (+, +)B = (+, -)C = (-, +) andD = (-, -)In A and D, the two numbers have the same signs and the multiplication gives a positive answer.In B and C, the two numbers have different signs and the multiplication gives a negative answer.
Multiplication or division of two numbers of opposite signs: negative*positive, positive*negative, negative/positive, and positive/negative. Addition of two negative numbers: -5 + -2 = -7 Multiplying pure imaginary numbers of the same 'sign' : 5i * 2i = -10. -3i * -4i = -12. Dividing pure imaginary numbers of different signs (this comes from the fact that 1/i = -i, and i/i = +1)
Positive.

If you're talking about multiplication or division, then opposite signs will result in a negative number.
It's a positive number. Here's the rule: In multiplication and division . . . -- If both numbers have the same sign, then the result of multiplying or dividing them is positive. -- If the two numbers have different signs, then the result of multiplying or dividing them is negative.
The four possible combinations are:A = (+, +)B = (+, -)C = (-, +) andD = (-, -)In A and D, the two numbers have the same signs and the multiplication gives a positive answer.In B and C, the two numbers have different signs and the multiplication gives a negative answer.
The answer will always be Negative in Sign. If they are the same sign, it will always be Positive in Sign.
rule where the answer will always be positive BECAUSE: Product means you're doing multiplication. positive x positive = positive negative x negative = positive positive x negative = negative negative x positive = negative

No, the rule for multiplication is much easier than that. If the two numbers have the same sign, then their product is positive. If they have different signs, then their product is negative.
Positive.
Like signs: When both numbers are either positive or negative, like: +6 and +4 Unlike signs; When one is either positive or negative, like he nd lo sn.x
These mnemonic devices were developed by SHERWIN E. BALBUENA, mathematics teacher of Cabitan NHS, Mandaon, Masbate, Philippines", to teach his students with disabilities the rules in operating signed numbers. LA US means "Like signs Add, Unlike signs Subtract". This device lets the student remember the rule in adding signed numbers. LP UN means "Like signs Positive, Unlike signs Negative". This device lets the student recall the rules in finding the product and quotient of two signed numbers.
