Unit 2: Integers Review

Front

What are integers?

Back

Integers are whole numbers that can be positive, negative, or zero. They do not include fractions or decimals.

Front

What is the coordinate plane?

Back

The coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis). Each point on the plane is defined by an ordered pair (x, y).

Front

What is the origin in the coordinate plane?

Back

The origin is the point where the x-axis and y-axis intersect, represented by the coordinates (0, 0).

Front

What are the four quadrants of the coordinate plane?

Back

Quadrant I: (+, +), Quadrant II: (-, +), Quadrant III: (-, -), Quadrant IV: (+, -).

Front

How do you add a positive integer and a negative integer?

Back

To add a positive integer and a negative integer, subtract the absolute value of the negative integer from the positive integer. The sign of the result is determined by the larger absolute value.

Front

What is the result of 7 + (-14)?

Back

Front

What is the order of operations in mathematics?

Front

What does the x-coordinate represent in an ordered pair?

Back

The x-coordinate represents the horizontal position of a point on the coordinate plane.

Front

What does the y-coordinate represent in an ordered pair?

Back

The y-coordinate represents the vertical position of a point on the coordinate plane.
