Front

What is the distance between two numbers on a number line?

Back

The distance between two numbers on a number line is the absolute value of the difference between them. It is always a positive value.

Front

How do you calculate the distance between -8 and 10?

Back

Distance = | -8 - 10 | = | -18 | = 18.

Front

What is the result of adding two negative integers, such as -9 and -5?

Back

The result is negative. -9 + (-5) = -14.

Front

What does the expression -4 + 7 represent on a number line?

Back

It represents moving 4 units to the left from 0 and then 7 units to the right, resulting in a final position of 3.

Front

How do you find the temperature after a drop?

Back

Subtract the drop from the initial temperature. For example, if the temperature is 6 degrees F and drops 9 degrees F, the final temperature is 6 - 9 = -3 degrees F.

Front

What is 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. For example, |-5| = 5.

Front

What is the result of -1 + 10?

Back

The result is 9.

Front

How do you represent a temperature drop of 9 degrees from 6 degrees?

Back

You represent it as 6 + (-9) = -3.

Front

What is the distance between -1 and 10?

Back

Distance = | -1 - 10 | = | -11 | = 11.

Front

What is the sum of -4 and 3?

Back

The sum is -1.
