Adding and Subtracting Integers

Front

What is the result of adding two negative integers?

Back

The result is always a negative integer. For example, -21 + (-14) = -35.

Front

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

Back

You add the absolute value of the positive integer to the negative integer. For example, -3 - 4 = -3 + (-4) = -7.

Front

What is the sum of two negative integers, -10 and -32?

Back

The sum is -42, as both integers are negative.

Front

What happens when you add a positive integer to a negative integer?

Back

The result depends on the absolute values of the integers. For example, -17 + 3 = -14.

Front

What is the result of 12 + (-20)?

Back

The result is -8, as you are effectively subtracting 20 from 12.

Front

Define 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. For example, |-5| = 5.

Front

How do you determine the sign of the result when adding integers?

Back

If both integers have the same sign, the result has that sign. If they have different signs, subtract the smaller absolute value from the larger absolute value and take the sign of the integer with the larger absolute value.

Front

What is the result of -5 + (-3)?

Back

The result is -8, as both integers are negative.

Front

What is the result of -10 - (-5)?

Back

The result is -5, as subtracting a negative is the same as adding a positive.
