Adding Integers

Front

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

Back

The result can be positive, negative, or zero, depending on the values of the integers. If the absolute value of the positive integer is greater, the result is positive; if the absolute value of the negative integer is greater, the result is negative.

Front

What is the sum of two negative integers?

Back

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

Front

How do you add two integers with the same sign?

Back

When adding two integers with the same sign, you add their absolute values and keep the common sign.

Front

What is the result of adding zero to any integer?

Back

The result is the integer itself, as zero is the additive identity.

Front

What is the additive inverse of an integer?

Back

The additive inverse of an integer is the number that, when added to the integer, results in zero.

Front

Calculate the sum: 3 + -7. What is the process?

Back

To calculate 3 + -7, subtract the absolute value of -7 from 3: 3 - 7 = -4.

Front

What is the result of adding two negative integers, for example, -14 and -3?

Back

The result is -17, as you add their absolute values (14 + 3 = 17) and keep the negative sign.

Front

How do you simplify the expression (-40) + (-39)?

Back

Add the absolute values: 40 + 39 = 79, then apply the negative sign, resulting in -79.

Front

What is the result of adding a positive integer to a negative integer, such as 33 + (-38)?

Back

Subtract the absolute value of -38 from 33: 33 - 38 = -5.

Front

What is the sum of -9 and -5?

Back

The sum is -14, as you add their absolute values (9 + 5 = 14) and keep the negative sign.
