Adding and Subtracting Integers

Front

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

Back

The result depends on the absolute values of the integers. If the absolute value of the negative integer is greater than the positive integer, the result will be negative. If the positive integer's absolute value is greater, the result will be positive.

Front

How do you subtract an integer from another integer?

Back

To subtract an integer, you can add its opposite. For example, to calculate a - b, you can compute a + (-b).

Front

What is the sum of two negative integers?

Back

The sum of two negative integers is always negative, and you add their absolute values.

Front

What is the result of subtracting 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

How do you simplify the expression -12 + 18 - (-3) - 22?

Back

First, simplify -12 + 18 = 6. Then, add 3 (from -(-3)) to get 9. Finally, subtract 22 to get -13.

Front

What is the result of -8 - (-6)?

Back

Subtracting -6 is the same as adding 6, so -8 - (-6) = -8 + 6 = -2.

Front

What is the definition of an integer?

Back

An integer is a whole number that can be positive, negative, or zero.

Front

What is the absolute value of an integer?

Back

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

Front

How do you determine the sign of the result when adding two integers with different signs?

Back

When adding integers with different signs, the result will have the sign of the integer with the larger absolute value.

Front

What is the result of adding two positive integers?

Back

The result of adding two positive integers is always a positive integer.
