Why is a negative times a negative a positive?
Here is a proof. Let a and b be any two real numbers. Consider the number x defined as x = ab + (-a)(b) + (-a)(-b). We can write this out differently as x = ab + (-a)[ (b) + (-b) ] Then, by factoring out -a , we find that x= ab + (-a)(0) = ab + 0 = ab. Also, x = [ a + (-a) ]b + (-a)(-b) And by factoring out b, we find that x=0 * b + (-a)(-b) = 0 + (-a)(-b) = (-a)(-b). Therefore x = ab and x = (-a)(-b) Then, by the transitivity of equality, we have ab = (-a)(-b).

What binary number is represented by the decimal number 11?
In binary this would be written as 1011. This is because in binary (from right to left) the digits in this number mean: (1 * 20) + (1 * 21) + (0 * 22) + (1 * 23). This, of course, is equal to (1 * 1) + (1 * 2) + (0 * 4) + (1 * 8), which equals 1 + 2 + 0 + 8, which equals 11 (in decimal).
Which fraction is equal to 0-4?
4
Explain why zero is a rational number?
zero is rational because it can be written as a fraction where the denominator is not equal to 0. it can be written as 0/1, 0/2, 0/3, etc
If a (0 0) and b (8 2) what is the length of ab?
The length of ab can be found by using the Pythagorean theorem. The length of ab is equal to the square root of (0-8)^2 + (0-2)^2 which is equal to the square root of 68. Therefore, the length of ab is equal to 8.24.
What does ab equals 1a plus 1B plus ab equal to?
ab=1a+1b a is equal to either 0 or two, and b is equal to a
Why is -10 to the power 0 equal to?
Do you mean "What is -10 to the power 0 equal to?" Any number raised to 0 evaluates to 1
What does the power of 0 mean?
Any number to the power of 0 is always equal to 1
What would you suggest when A crossB equals 0 and AB equals 0?
Assuming that cross means 'divide' B is equal to 0
What number is divided by 4 and 6 equal?
If you mean to ask what number results in the same answer when divided by either 4 or 6, the only number that works is zero. 0/4 = 0/6 = 0
What number is equal to a opposite?
the number 0 is always equal to its opposite
Why does a negative times a negative always equal a positive?
There are many intuitive explanations that show it works. For example, you can look at debt as a negative number or you can use the number line to see why negative times negative is a positive. None of these is really a proof. In fact, since any negative number is really the same positive number multiplied by -1, i.e. -5=5x-1 when we really need to ask only why is -1x-1=1. One good, but often not satisfying, answer is that if we use any other convention, then it won't work. The fact is, it is a convention. For the mathematical purist, here is a nice proof that two negatives multiplied together equal a positive Let a and b be any two real numbers. Consider the number n defined by n = ab + (-a)(b) + (-a)(-b). We can write n= ab + (-a)[ (b) + (-b) ] if we just actor out -a = ab + (-a)(0) = ab + 0 = ab. Also, n = [ a + (-a) ]b + (-a)(-b) if we factor out b = 0 * b + (-a)(-b) = 0 + (-a)(-b) = (-a)(-b). So we have n = ab and n = (-a)(-b) Hence, by the transitivity of equality, we have ab = (-a)(-b) and the proof is complete.
What is the answer to x-ab?

What is the answer when Ab is not equal to 0 -12a cubed times b squared over 6ab squared?

Why is a negative times a negative a positive?

Therefore x = ab and x = (-a)(-b) Then, by the transitivity of equality, we have ab = (-a)(-b).
Is it possible to divide 15 by a mixed number and get a quotient that is grater than 15?
I assume that by a mixed number you mean a number of the form ab/c where a is an integer greater than 0 (otherwise the number would be a simple fraction), the answer is No.
