any negative number -n can be written as -1*n (minus 1 times that number). so, multiplying two negative numbers together:
-n * -m = -1*n * -1*m = -1*-1*n*m = n*m (which is always positive)
-6*-9 = -1*-1*6*9 = 6*9 = 54

What are some Real examples for negative slope and positive slope?
A positive slope is simply a slope going upward on a graph from left to right. A negative slope is a slope going downward from left to right. Often, negative slopes are the reverse of positive slopes and are both depending on the person's direction.
When you square a negative number is it positive or negative?
The square of a real number is always positive no matter which real number you start with. Therefore, a negative number squared is positive. For example: 2 * 2 = 4, -2 * -2 = 4.
What are some examples of negative numbers in daily life?
There are lots of situations in the real world in which there are opposites, which can conveniently be expressed with positive/negative numbers. Here are some examples:Having money (positive), having a debt (negative)Getting a profit (positive) or a loss (negative) with a business ventureAn altitude above (positive) or below (negative) sea levelGaining points or losing points in a gameMoving in one direction or in the opposite direction. In this case, it is quite arbitrary which direction is chosen as positive.
What are the two types of real number?
Negative and positive
How does the sign of a determine the number of real fourth roots of a and the number of real fifth roots of a?
If "a" is positive, it will have two fourth roots, one will be positive and one will be negative it will have one fifth root, which will be positive. If "a" is negative, it will have one fourth root, which will be negative. it will have one fifth root, which will be negative.
What are some examples of real life situations to explain why a negative number times a negative number will give a negative number?
A negative number times a negative number gives you a POSITIVE number, not a negative number.
A negative times a postitive gets you?
A negative (real) number multiplied by a positive (real) number will always result in a negative (real) number.
What are some examples of real life situations to explain why a negative number times a positive number will give a negative number?
cold temperature sub-basement debt walking backward
What about a real life situation to explain why a negative times a negative number will give a positive number?
there is no real life situation
Is it possible to find the square root of a negative number in the real number system?
No. There is no real number which multiplied by itself forms a negative number.A negative times a negative is a positive, and only a positive times a negative is a negative.However, in calculus there is an "imaginary value" (called i ) which represents the square root of -1.Square roots of larger negative numbers are represented by the square of the absolute value times i .
Why is it impossible to get a negative answer when you square any number?
V kno that- x- is +. Now when u sqare a negative no it means occouring 2 times and cancel out each other. For example- -2 x -2=4 ============================ (a second answer.) Every real number is either negative, positive or zero. When you square a number, you multiply it by itself, so if you square a negative number, you are multiplying a negative by a negative which gives a positive. If you square a positive, you multiply a positive by a positive and get a positive. If you square 0 , get 0. Therefore, in no case is the answer negative. ( It is harder to explain why a negative times a negative is positive.)
When squaring a negative number if the factor is a negative and the exponent is positive will your answer be negative or positive?
If you square any real number it will always be positive.

Why cant you evaluate the square root of negative twenty five using real numbers?
using basic math principles, you can't find the square root of a negative number because in order for a number to be a square root, you have to multiply it by itself to get your radical. since a negative times a negative and a positive times a positive are both positive, it is impossible to find the square root of a negative number
What is the square root of negative 62?
If you have not studied complex numbers, then the answer is as follows:The rules of multiplication for real numbers are thata positive times a positive is a positive, anda negative times a negative is a negative.[Also, 0 times 0 is 0].The upshot of all that is the square is never negative. And so, the answer is that there is no real number whose square is -62.If you have studied complex numbers then you should not be asking such basic questions! Still, the square roots of -62 are the complex pair ±7.874i where i is the imaginary square root of -1.
