Final Review Part 1

Front

What is the additive inverse of a number?

Back

The additive inverse of a number is the value that, when added to the original number, results in zero. For example, the additive inverse of 5 is -5.

Front

How do you change a subtraction problem to an addition problem using the additive inverse?

Back

To change a subtraction problem to an addition problem, you can add the additive inverse of the number being subtracted. For example, -16 - 13 can be changed to -16 + (-13).

Front

What is the solution to the equation -(-x + 2) - 4x?

Back

The solution is -3x - 2.

Front

If twelve PTA members need to raise $527.86 and have already raised $349.11, how much must each member raise?

Back

Each member must raise $14.90.

Front

What property allows you to regroup numbers in an addition problem?

Back

The Associative Property allows you to regroup numbers in an addition problem.

Front

What is the Commutative Property of Addition?

Back

The Commutative Property of Addition states that changing the order of the addends does not change the sum. For example, a + b = b + a.

Front

What is the Distributive Property?

Back

The Distributive Property states that a(b + c) = ab + ac. It allows you to distribute a multiplier across terms in parentheses.

Front

What is the Inverse Property of Addition?

Back

The Inverse Property of Addition states that for any number a, there exists a number -a such that a + (-a) = 0.

Front

What is the solution to the equation -6 - (-5)?

Back

The solution is -6 + 5.

Front

What is the difference between the Associative and Commutative Properties?

Back

The Associative Property deals with grouping of numbers, while the Commutative Property deals with the order of numbers.
