Why does a positive number divided by a negative number equal a negative number instead of infinity?

If you think about it, the division simbol means how many times a number can go into another number, so a positive number, like 5 goes into a negative number, like -25, -5 times, because the -5 is less than 1, and 5 cant go into anything less than one even once, so it goes in a negative amount of times. I'm not sure why a positive number divided by a negative number would be infinity.

When subtracting a negative number why do you move to the right on the number line instead of the left?
Subtracting a negative number is the same as adding a positive number. Also, adding a negative number is the same as subtracting a positive number. -7 + (-5) = -7 - 5 = -12 -7 - (-5) = -7 + 5 = -2
How many zeros does a googol have?
Googol is as far away from infinity as zero, but instead of being lower, it is higher.
What is a smaller negative?
When comparing negative numbers or a negative number and a positive number, the word "smaller" is confusing because it is unclear whether you mean that the number is less than another number or that the absolute value of the number is less than the absolute value of another number. You should use the phrase "less than" instead. A number's absolute value is how far it is from zero; for negative numbers think of it as the number without the negative sign. Negative eleven is less than negative three because negative eleven is farther left on the number line, but the absolute value of negative three, which is shown as |-3|, is less than the absolute value of negative eleven because negative three is closer to zero.
What is the lowest positive integer greater than one which when divided by five or eight leaves a remainder of one?
6. 6 % 5 = 1, where % is the modulo operator (a fancy way of saying that it finds the remainder). If you were instead dividing by 8 and not 5, then the answer would be 9.
Why is subtracting a negative number the same as adding a positive number?
The best way to understand this is probably by thinking of the real number line:Subtracting can be thought of as switching directions as you move along the number line. For instance, 5 + 3 means you start at position 5 on the positive side of the number line and move to the right, the positive direction, 3 integral ticks. However, 5 - 3 means you switch directions. Now, you start at position 5 and move left, the negative direction, 3 integral ticks.Negation can be thought of in the same manner as subtraction; i.e. as a directional change on the number line. Using the above example, that would mean that for 5 + (-3) you would once again start at position 5 on the positive side of the number line and start to move right, since that what addition means. However, the negative sign in front of the 3 forces you to change direction, so instead you end up moving left 3 integral ticks.Now, to finally answer your question. 5 - (-3), using the number line, would again mean that you would start at position 5 on the positive side. The subtraction operation, as explained above, means that you would move left 3 ticks instead of right. However, the negation of 3, also explained above, means that you would once again switch directions, this time from left to right, and ultimately move 3 ticks that way, the positive direction. Hopefully, you can see that the end result of both 5 + 3 and 5 - (-3) has you moving 3 ticks in the same direction, that being the positive direction, which is why they can be thought of as the same operation.
What is infinity times infinity minus infinity?
Firstly, infinity is not a number (at least in lower level mathematics). You must instead use the language of limits to describe infinity. Using limits, a function which diverges to infinity multiplied by a function which diverges to infinity has a product which also diverges to infinity. However, taking this product, and subtracting away a function which diverges to infinity is "of indeterminate form". It might converge to zero, it might be diverge to positive infinity, it might diverge to negative infinity, or it might converge to a constant. In order to figure out which one of these possibilities applies, you must get the indeterminate form into the form infinity divided by infinity or 0/0 and then apply L'Hospital's rule. Edit: Just a pet peeve of mine. It's L'Hôpital, not L'Hospital. Even textbooks don't spell it right.
How do you write in interval notation 0 less than x less than positive infinity?
(0, infinity) Note that you should use the infinity sign instead of the word (the sideways 8).
What is infinity is divided by infinity?
1To touch on this whatever you take and divide by the same number will always give you one.2Infinity divided by infinity is not equal to 1, But it is undefined, not another infinity. This would help you:First, I am going to define this axiom (assumption) that infinity divided by infinity is equal to one:∞-∞= 1Since ∞ = ∞ + ∞, then we are going to substitute the first infinity in our axiom:∞ + ∞---∞= 1The next step is to split this fraction into two fractions:∞-∞+ ∞-∞= 1Next, substitute the axiom twice into the equation, we get:1 + 1 = 1Finally, this can be rewritten as:2 = 1Therefore, infinity divided by infinity is NOT equal to one. Instead we can get any real number to equal to one when we assume infinity divided by infinity is equal to one, so infinity divided by infinity is undefined.
Why product of two positive numbers is positive?
Cuz there's nothing to make it negative.... Just think of it as regular multiplying instead... Unless there is a negative...

What type of number is negative 64 squared?
The question is ambiguous. If you meant negative (64 squared), the value is -4096, which is a negative integer. If, instead, you meant (negative 64) squared, the value is +4096, a positive integer.
What is Gaelic for no?
Irish and Scottish Gaelic have no words for yeas and no. Instead the verb is repeated in a negative or positive form. 'Were you there?' 'I was not' (no). 'I was." (yes)
