What is a negative number?

A negative number is a numerical value that is less than zero. It represents a quantity or value that is below a reference point or zero on a number line. Negative numbers are used to denote situations such as debts, losses, or temperatures below zero.

How can negative numbers be represented on a number line?

Negative numbers can be represented on a number line by placing them to the left of zero. The further left a number is on the number line, the smaller it is. Each negative number is represented by a point on the number line, with increasing numerical values as you move to the left.

What is the opposite of a negative number?

The opposite of a negative number is a positive number.

How are negative numbers added and subtracted?

Negative numbers are added by treating the negative sign as a sign of subtraction. For example, adding -3 and -2 would be equivalent to subtracting 3 from 2, resulting in -5. When subtracting negative numbers, it is equivalent to adding the opposite value. So, subtracting -3 from -7 would be the same as adding 3 to 7, resulting in -4.

How can you determine the sign of the product when multiplying negative numbers?

To determine the sign of the product when multiplying negative numbers, you need to consider the number of negative factors being multiplied. If there is an even number of negative factors, the product will be positive. If there is an odd number of negative factors, the product will be negative.

How are negative numbers multiplied by positive numbers?

When negative numbers are multiplied by positive numbers, the result is always a negative number. This is because multiplying by a negative number changes the direction of the quantity being multiplied. So, when a negative number is multiplied by a positive number, the negative sign carries over and the result is a negative number.

How are negative numbers divided?

When dividing negative numbers, the rules are the same as dividing positive numbers. If both numbers being divided are negative, the result will be positive. If only one of the numbers is negative, the result will be negative. In other words, the negative sign in front of a number is treated as a separate operator that determines the sign of the result.

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 a positive number. For example, (-2)^2 = 4. When a negative number is square rooted, the result is a complex number. For example, the square root of -16 is 4i, where i is the imaginary unit equal to the square root of -1.

Can negative numbers be less than zero?

No, negative numbers are by definition less than zero. Negative numbers represent values that are below zero on the number line, indicating a deficit or a decrease from zero.

How can you solve equations involving negative numbers?

To solve equations involving negative numbers, you can treat the negative numbers just like positive numbers by following the same rules of algebra. When adding or subtracting negative numbers, remember to pay attention to the signs. When multiplying or dividing, a negative number multiplied or divided by a positive number results in a negative answer, and a negative number multiplied or divided by a negative number results in a positive answer. Ultimately, the key is to understand the rules of manipulating negative numbers while solving the equations.
