Well, honey, any number that doesn't make sense in the context of the problem would be a no-go. For example, negative numbers for measuring height or fractions for counting people - that's just a recipe for disaster. Stick to numbers that actually make sense in the real world, and you'll be golden.
No, they are quite real. It is just that in some situations it makes sense to use negative numbers, in others not.
The opposite of 0 for negative numbers is not specifically defined, as 0 itself is neither positive nor negative. However, the concept of opposites can be applied to negative numbers, where the opposite of a negative number is its positive counterpart. For example, the opposite of -5 is +5. In this sense, the opposite of 0 would simply be the notion of moving into the negative or positive realms, but 0 itself remains neutral.
It depends; there is no right or wrong answer. Take into account the size of the numbers involved, the amount of space you have, and the type of numbers that would make sense, both with the numbers involved and in a practical sense - your numbers may all be multiples of seven, but don't make it harder than it needs to be. There are honestly a countless number of variables involved, so mostly it's up to you to decide what makes sense.
Let's assume for a moment we're not thinking about negative numbers. Only counting numbers from 0-49, there is the same number even as odd so the answer is no. If you didn't include 0, then the answer would be yes. If you do include negative numbers, then there are an infinite number of both odd and even numbers. In this case it doesn't seem to make sense to say there are more odd numbers than even numbers so the answer is no. In short: No. Yes if it's only 1-49.
If you add the modern values to it it wont make sense

The domain is the set of values that x may take that gives back an answer that makes sense. The range is the set of values that are possible results of the function. the "log" function does not accept 0 or negative values on its domain and returns negative, zero and positive numbers (ie all real values). The next function does not appear properly but you could figure it out

an object cannot take up a negative amount of space
That really depends on the situation. Just as there are cases where fractional numbers make sense and others where they don't, and just as there are cases where negative numbers make sense and others where they dont, likewise, there are situations in which complex numbers (with an imaginary part) make sense, and others in which they don't. In many practical cases they don't make sense; in this case, the non-real solution is an indication that there is no practical solution. Example: Use the quadratic formula to determine at what time an object, thrown upwards, will reach a certain height. If you get a complex solution (the discriminant is negative), this means the object will NEVER reach the specified height; it will fall back down before it reaches the desired height. In this case, the variable "time" can only have real values - imaginary values don't make physical sense. However, please note that there are also situations in which complex numbers DO make sense.

No, dissolved oxygen values cannot be negative. Dissolved oxygen levels in water are typically measured in milligrams per liter (mg/L) or parts per million (ppm) and will always be a positive value. Negative values would not make physical sense in this context.
There are many different contexts in which lambda is used. It is not possible to make sense of the question without knowing the context.
The aforementined word negative numbers are relative but in the real sense of trading there are certain parameters we are going to consider before selecting numbers in trading to have more light on this,there is a software that helps in executing this.Here is where you can have more tips on this.debtsolverreviews.blogspot.com

It depends on the type of problem you are talking about. For example, in problems just concerning numbers and no units or words, negatives would make sense and could be logical. However, in word problems, it would obviously be illogical and absurd to answer -5 when asked, per se, how many miles Johnny has walked, or how many oranges Suzie has.
