Why is the number line of a number is never negative?
A number line can have both positive and negative numbers. You can put the number line in any position, but often it is represented so that numbers to the right of zero are positive, and numbers to the left of zero, negative.
How does weather use negative numbers?
When determining temperature in the negative range, which is more often seen in the Celsius scale versus the Fahrenheit scale. Negative numbers in Celsius are below the freezing point of water.Reported changes in tides and barometric levels use negative numbers as well, although the readings themselves would not be negative.
What are 10 real life situations do we use negative numbers?
Negative numbers are often used when there are opposites; in this case, one of the opposites is assigned positive numbers, the other, negative numbers. For example, you might:* Use positive numbers for positions above sea level, and negative for below sea level. * Use positive numbers for money you have in your bank account; negative numbers for money you owe others. * Use positive numbers for northern latitudes, and negative numbers for southern latitudes. Or vice versa. * There are lots of other situations where opposites are involved, but you probably get the idea.
Two numbers are if their product is -1?
Two numbers are negative reciprocals if their product is -1. The numbers 1/2 and -2 are negative reciprocals. Their product is -1. This is often seen in problems involving the slopes of two lines. The slopes of perpendicular lines are negative reciprocals. Their product is -1.
What is the definition of negative numbers?
A negative number is any real number that is less than zero. Such numbers are often used to represent the amount of a loss or absence. For example, a debt that is owed may be thought of as a negative asset, or a decrease in some quantity may be thought of as a negative increase. Negative numbers are also used to describe values on a scale that goes below zero, such as the Celsius and Fahrenheit scales for temperature.
How do weather experts use negative numbers?
Decreases are often represented by negative numbers. Temperatures outside of most tropical regions are occasionally negative on the commonly used scales.

The set of positive whole numbers negative whole numbers and 0?
The set of integers, often is denoted by Z.
How do you use negative numbers during everyday life?
Negative numbers are often found in measurements. They are used to represent numbers that have sunk below 0 (ex: temperature, debt) or have become the inverse of a number (velocity, energy, negative exponents). Without machines of sorts negative numbers are very rare in everyday life, but so are very large numbers or very small numbers.

Do 2 positive numbers make a positive answer?
Often, but not always. It depends upon what you do with them. If the numbers are not equal, and you subtract the larger from the smaller, the answer will be negative.

Statment between the magnitude of a earthquake and how often earthquakes of the magnitude occur?
One statement you could write is that "Earthquakes of higher magnitudes are much rarer than those of lower magnitudes". The magnitude of earthquakes is a logarithmic scale, so a magnitude of 8 is TEN TIMES more powerful than a magnitude 7. This is why earthquakes of higher magnitudes are so much rarer than those of lower magnitudes.
The number 0 is not an element of the set of natural numbers true or false?
True. Zero is in the set of whole numbers, integers, rational numbers and real numbers but not natural numbers. Natural numbers are often referred to as the "counting numbers" or how you learned to count. When we are teaching little children numbers, we never start with zero or negative numbers - just 1, 2, 3...
