Adding and Subtracting Integers

Front

What is the result of adding a positive integer and a negative integer?

Back

The result can be found by subtracting the absolute value of the negative integer from the positive integer. If the absolute value of the negative integer is greater, the result will be negative.

Front

How do you subtract a negative integer from a positive integer?

Back

Subtracting a negative integer is the same as adding its absolute value. For example, a - (-b) = a + b.

Front

What is the difference between two integers?

Back

The difference is found by subtracting one integer from another. The result can be positive, negative, or zero.

How do you represent temperatures above and below sea level using integers?

Back

Temperatures above sea level are represented as positive integers, while temperatures below sea level are represented as negative integers.

Front

What is the result of -4 - (-2)?

Back

The result is -4 + 2, which equals -2.

Front

How do you find the absolute value of an integer?

Back

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

Front

What is the sum of two negative integers?

Back

The sum of two negative integers is always a negative integer.

Front

If the high temperature is 4 degrees and the low temperature is -7 degrees, how do you find the difference?

Back

To find the difference, subtract the low temperature from the high temperature: 4 - (-7) = 4 + 7 = 11 degrees.

Front

What happens when you add two positive integers?

Back

The sum of two positive integers is always a positive integer.

Front

How do you interpret a negative result in a real-world context, such as depth below sea level?

Back

A negative result indicates a position below a reference point, such as sea level, which is often represented as zero.
