An absolute value expression must always be a non-negative expression. Meaning it can equal zero, or it can equal any positive number, but it can never equal a negative number.
How do you isolate the absolute value in an absolute value expression or inequality? You isolate the absolute value by moving all other terms to the other side of the equal or inequality sign.
If "a" is a positive number, how many solutions are there? There will always be two solutions
How many solutions are there when an isolated absolute value equals a negative number? None, there are no solutions.

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:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

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.
