Math - chapter 5

Front

What is the process to order a set of numbers from least to greatest?

Back

To order a set of numbers from least to greatest, compare each number and arrange them in ascending order, starting with the smallest number.

Front

What is the opposite of a number?

Back

The opposite of a number is the number that is the same distance from zero on the number line but in the opposite direction.

Front

What are the four quadrants of a Cartesian coordinate system?

Back

The four quadrants are: Quadrant I (x > 0, y > 0), Quadrant II (x < 0, y > 0), Quadrant III (x < 0, y < 0), Quadrant IV (x > 0, y < 0).

Front

How do you determine the absolute value of a number?

Back

The absolute value of a number is its distance from zero on the number line, regardless of direction. It is always a non-negative value.

Front

What is the significance of the number line in mathematics?

Back

The number line is a visual representation of numbers in order, allowing for the comparison of values, understanding of positive and negative numbers, and the concept of absolute value.

Front

How do you identify the quadrant of a point in the Cartesian plane?

Back

To identify the quadrant of a point (x, y), check the signs of x and y: Quadrant I (both positive), Quadrant II (x negative, y positive), Quadrant III (both negative), Quadrant IV (x positive, y negative).

Front

What is the definition of a rational number?

Back

A rational number is any number that can be expressed as the quotient or fraction of two integers, where the denominator is not zero.

Front

What is the difference between integers and whole numbers?

Back

Integers include all positive and negative whole numbers, as well as zero. Whole numbers include all non-negative integers (0, 1, 2, 3, ...).

Front

How do you locate a number on a number line?

Back

To locate a number on a number line, find the point that corresponds to the value of the number, moving right for positive numbers and left for negative numbers.

Front

What is the concept of ordering fractions?

Back

To order fractions, convert them to a common denominator or compare their decimal equivalents to arrange them from least to greatest.
