What does it mean to add integers?

Back

Adding integers involves combining their values. If both integers are positive, the result is positive. If both are negative, the result is negative. If one is positive and one is negative, subtract the smaller absolute value from the larger absolute value and take the sign of the integer with the larger absolute value.

What does it mean to subtract integers?

Back

Subtracting integers is the same as adding the opposite. For example, to subtract a positive integer, add its negative counterpart.

Front

What is the product of two integers?

Back

The product is the result of multiplying two integers. If both integers have the same sign, the product is positive. If they have different signs, the product is negative.

Front

What is the quotient of two integers?

Back

The quotient is the result of dividing one integer by another. If the signs of the integers are the same, the quotient is positive; if they are different, the quotient is negative.

Front

What is the opposite of an integer?

Back

The opposite of an integer is the integer that is the same distance from zero on the number line but in the opposite direction.

Front

What is the distance between two integers on a number line?

Back

The distance between two integers is the absolute value of the difference between them.

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, the absolute value of -5 is 5.
