Integers- add/subtract

Front

What is the result of adding two integers with different signs, such as -3 and 5?

Back

To add integers with different signs, subtract the smaller absolute value from the larger absolute value and take the sign of the integer with the larger absolute value. In this case, -3 + 5 = 2.

Front

How do you represent the addition of a positive integer and a negative integer, such as 6 and -9?

Back

When adding a positive integer and a negative integer, subtract the absolute value of the negative integer from the positive integer. Here, 6 + (-9) = 6 - 9 = -3.

Front

What does the equation 1 - 2 represent in terms of integers?

Back

The equation 1 - 2 can be rewritten as 1 + (-2). It represents the addition of a positive integer and a negative integer, resulting in -1.

Front

What is the result of -6 + 4?

Back

To add -6 and 4, subtract the absolute value of 4 from the absolute value of -6. Thus, -6 + 4 = -2.

Front

What is the sum of -7 and 4?

Back

To find the sum of -7 and 4, subtract the absolute value of 4 from the absolute value of -7. Therefore, -7 + 4 = -3.

Front

What is the rule for adding two positive integers?

Back

When adding two positive integers, simply add their absolute values. For example, 3 + 5 = 8.

Front

What is the rule for adding two negative integers?

Back

When adding two negative integers, add their absolute values and keep the negative sign. For example, -3 + (-5) = -8.

Front

How do you subtract integers?

Back

To subtract an integer, add its opposite. For example, to calculate 5 - 3, you can rewrite it as 5 + (-3) = 2.

Front

What is the result of adding zero to any integer?

Back

Adding zero to any integer does not change its value. For example, 5 + 0 = 5.

Front

What is the concept of absolute value in relation to integers?

Back

The absolute value of an integer is its distance from zero on the number line, regardless of direction. For example, |-3| = 3.
