Does division and multiplication involve negatives?
Not by necessity, but multiplication and division aredefined for negative numbers.
When a division problem has numbers of opposite signsthe quotient is?
Negative.
How do you divide a negative number?
Same as regular division with positive numbers. Its just that a negative number divided by another negative numbers equals a positive number.
What happen when you divide negative and positive number?
When you divide or multiply positive and negative numbers, you first do the division or multiplication as normal. The next step is to assess whether or not the answer will be negative or positive. If the two numbers of the question were the same (negative and negative or positive and positive) then the answer will be positive. If the two numbers in the question were different (one negative and one positive) then the answer will be negative. Thus, if you divide a negative number by a positive number, the result will be the same as normal division, but the answer will be negative.
What combination of signed numbers always leads to a negative number?
If you're talking about multiplication or division, then opposite signs will result in a negative number.
Why are positive rational numbers greater than negative rational numbers?
Because 1. Positive integers are greater than negative integers, and 2. Division by a positive number preserves the order.
When multiplying and dividing rational numbers how do you know if you're into me positive negative?
It the signs of the two numbers that you are multiplying or dividing is the same, then the answer is positive, otherwise the answer is negative. Remember though, that division by 0 is not defined.
Positive and negative what is the final result?
It depends on the operation and values of the positive and negative. For example, in multiplication or division a positive and negative will be a negative. In addition or subtraction, it depends on the absolute value of the original numbers.
Explain how you can find the sign of the product of two or more rational numbers?
Negative times negative equals positive. Positive times positive equals positive. Positive times negative equals negative. If you have more than two numbers, multiply the first two and then apply these rules to each successive number in turn.
What is 63 divided by negative 7?
9
What operations will always produce a negative number?
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)
Division of negative signs?
The rules for division are exactly the same as the rules for multiplication. * Division (or multiplication) of a positive number by a positive number = positive * Division of a positive number by a negative number = negative * Division of a negative number by a positive number = negative * Division of a negative number by a negative number = positive If you have trouble remembering any of these, just try out a sample division on any calculator - for instance, if you divide (-1) / (-1) you get +1.
