Equation Properties

Properties used to solve algebraic equations

TermDefinition
Additive Inverse When you add a number and its opposite you will get a sum of zero. Ex. 4 + -4 = 0
Multiplicative Inverse When you multiply a number by its reciprocal you will get a product of one. Ex. 4 x (1/4) = 1
Additive Identity When you add zero to a number the number remains the same Ex. 4 + 0 = 4
Multiplicative Identity When you multiply a number by 1 the number remains the same. Ex. 5 x 1 = 5
Addition Property of Equality If two expressions are equal, and you add the same value to both expressions, the two expressions remain equal. Ex. (9 = 9) (9 + 2 = 9 + 2) (11 = 11)
Subtraction Property of Equality If two expressions are equal, and you subtract the same value from both expressions, the two expressions remain equal. Ex. (9 = 9) (9 - 2 = 9 - 2) (7 = 7)
Multiplication Property of Equality If two expressions are equal, and you multiply the same value to both expressions, the two expressions remain equal. Ex. (9 = 9) (9 x 2 = 9 x 2) (18 = 18)
Division Property of Equality If two expressions are equal, and you divide both expressions by the same number, the two expressions remain equal. Ex. (8 = 8) (8 / 2 = 8 / 2) (4 = 4)

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
