What are negative numbers?

Negative numbers are numbers less than zero on the number line. They indicate a deficit or a decrease in quantity, such as -1, -2, -3, and so on. Negative numbers are used in various mathematical operations and real-life situations to represent debt, loss, temperature below zero, and other scenarios where values are lower than a reference point.

How are negative numbers represented on a number line?

Negative numbers are represented on a number line by placing them to the left of zero. The further to the left a number is on the number line, the smaller its value. The placement of negative numbers on a number line allows for visualizing their relationship to zero and positive numbers, enabling mathematical comparisons and calculations.

What is the definition of absolute value?

The absolute value of a number is the distance of that number from zero on the number line, regardless of its sign. It is always a non-negative value, as it represents the magnitude of the number without consideration of its direction.

How do you compare two negative numbers?

To compare two negative numbers, you simply compare them as you would with positive numbers. The number closer to zero is considered greater, while the number farther from zero is considered smaller. In other words, the negative number with the greater absolute value is considered less than the negative number with the smaller absolute value.

How are negative numbers used in real-life situations?

Negative numbers are used in real-life situations to represent a variety of scenarios, such as debt, temperatures below zero, loss in financial investments, decrease in stock prices, decline in sales figures, and altitude below sea level. They provide a way to express values that are less than zero and play a crucial role in mathematics, science, economics, and everyday life for dealing with situations that involve a decrease or a shortfall.

Can negative numbers be added or subtracted? If so, how?

Yes, negative numbers can be added or subtracted like any other numbers. To add negative numbers, simply add them as you would positive numbers but include the negative sign in the result. For subtracting negative numbers, you can either convert the subtraction into addition by changing the sign of the number being subtracted, or directly subtract the numbers while maintaining the negative signs. The key is to pay attention to the signs and apply the rules of addition and subtraction accordingly.

How do you multiply or divide negative numbers?

When multiplying or dividing negative numbers, the basic rule is that if the signs of the numbers are the same, the result is positive. If the signs are different, the result is negative. For multiplication, simply multiply the absolute values of the numbers and then determine the sign of the result based on the rule. When dividing negative numbers, it is similar to multiplication; divide the absolute values and then determine the sign of the result according to the rule.

What is the difference between positive and negative numbers?

Positive numbers are greater than zero, while negative numbers are less than zero. Positive numbers are typically represented with a plus sign (+), while negative numbers are represented with a minus sign (-). In addition, positive numbers indicate gain or increase in value, while negative numbers indicate loss or decrease in value.

How are negative numbers used in temperature measurements?

Negative numbers are used in temperature measurements to represent values below zero on the Celsius or Fahrenheit scales. In physics and engineering, negative temperatures can also be used to denote values below absolute zero on the Kelvin scale, where particles have higher energies than at any positive temperature. This allows for a complete and accurate representation of temperature variations and calculations in a wide range of scientific fields.

Can negative numbers be squared or square rooted?

Yes, negative numbers can be squared and square rooted. When a negative number is squared, the result is always positive. For example, (-2) squared equals 4. When a negative number is square rooted, the result is a complex number, rather than a real number, because there is no real number that can be multiplied by itself to result in a negative number.
