Adding and Subtracting Integers

Front

What is the result of adding a positive integer to 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.

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, 16 - (-9) is the same as 16 + 9.

What is the difference between two temperatures when one is below zero?

Back

To find the difference, subtract the lower temperature from the higher temperature, considering their absolute values.

If a bank account balance is negative, what does it indicate?

Back

A negative balance indicates that the account is overdrawn, meaning the account holder has spent more money than they have deposited.

What is the formula for finding the change in a bank account after a deposit?

Back

Change = New Balance - Old Balance. If the old balance is negative, the change will be the sum of the absolute value of the old balance and the deposit.

How do you represent a temperature drop in terms of integers?

Back

A temperature drop can be represented as a negative change. For example, if the temperature drops from -9 degrees to -11 degrees, the change is -2 degrees.

Front

What is the result of subtracting a negative number from a positive number?

Back

The result is always greater than the positive number. For example, 232 - (-84) equals 232 + 84.

Front

What does it mean to add integers with different signs?

Back

When adding 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.

Front

How do you calculate the absolute value of a negative integer?

Back

The absolute value of a negative integer is its positive counterpart. For example, the absolute value of -7 is 7.

Front

What is the significance of zero in integer addition and subtraction?

Back

Zero is the additive identity, meaning adding zero to any integer does not change its value.
