Integers Operations Flashcard

Front

What is an integer?

Back

An integer is a whole number that can be positive, negative, or zero. Examples include -3, 0, and 5.

Front

How do you add two integers with the same sign?

Back

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

Front

How do you add two integers with different signs?

Back

When adding two 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. For example, 5 + (-3) = 2.

Front

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

Back

Subtracting a negative integer is the same as adding its positive counterpart. For example, 5 - (-3) = 5 + 3 = 8.

Front

What is the product of two negative integers?

Back

The product of two negative integers is positive. For example, -4 x -5 = 20.

Front

What is the product of a positive integer and a negative integer?

Back

The product of a positive integer and a negative integer is negative. For example, 4 x -5 = -20.

Front

How do you find 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, | -7 | = 7 and | 7 | = 7.

Front

What is the range of a set of integers?

Back

The range is the difference between the highest and lowest values in the set. For example, the range of -3, 0, and 5 is 5 - (-3) = 8.

Front

What does it mean to evaluate an expression with integers?

Back

Evaluating an expression with integers means to calculate its value by performing the operations indicated. For example, evaluate 3 + (-2) = 1.

Front

What is the sum of 7 and -5?

Back

7 + (-5) = 2.
