Integer Addition and Subtraction

Front

What is the concept of elevation in terms of sea level?

Back

Elevation refers to the height of a point above or below sea level. Positive values indicate heights above sea level, while negative values indicate depths below sea level.

Front

How do you calculate the difference between two elevations?

Back

To calculate the difference between two elevations, you subtract the lower elevation from the higher elevation. If one is above sea level and the other is below, you add their absolute values.

Front

What is the result of subtracting a negative number from a negative number?

Back

Subtracting a negative number is equivalent to adding its absolute value. For example, -8 - (-6) = -8 + 6 = -2.

Front

How do you represent a loss in yards in a football game?

Back

A loss in yards is represented as a negative value. For example, a loss of 12 yards is represented as -12 yards.

Front

What is the final position of an object after multiple movements?

Back

To find the final position, you sum all movements, considering the direction (positive for upward or forward, negative for downward or backward).

Front

If a diver is at -150 feet and descends 30 feet, what is the new depth?

Back

The new depth is calculated by adding the descent to the current depth: -150 - 30 = -180 feet.

Front

What does it mean to rise in elevation?

Back

To rise in elevation means to move to a higher point above sea level, which is represented by a positive change in value.

Front

How do you calculate total loss in a series of negative movements?

Back

To calculate total loss, sum all negative movements. For example, a loss of 12 yards and a penalty of 5 yards results in a total loss of 12 + 5 = 17 yards.

Front

What is the significance of absolute values in elevation problems?

Back

Absolute values are used to determine the distance from sea level, regardless of whether the elevation is above or below sea level.

Front

How do you interpret a final elevation of 2 feet?

Back

A final elevation of 2 feet indicates that the object is 2 feet above sea level.
