QuestionAnswer
Commutative 5+2=2+5 or ab=ba
Additive Inverse 7+(-3)=7-3 or a-b=a+(-b)
Associative Property/Grouping Property (8+2)+3=8+(2+3) or (ab) c=a (bc)
Additive identity 6+0=6 or abc+0=abc
Multiplicative Identity 3*1 =3 or xyz*1 =xyz
Multiplicative Property of Zero 7*0 =0 or ab*0 =0
Distributive 5(6+2) = 5(6) + 5(2) or x(y-z) = xy - xz
Comparison Property given two numbers, x and y, either x >y, x <y, or x=y
Density Property The number line is forever dense. Given any two numbers x and y there is always a number between them.
Reflexive 8 = 8 or 2a +7= 2a+7. Anytime you check an equation you are seeking a true statement.
Symmetric If 3+8 =11 then 11= 3+8. or if a+b =c then c= a+b
Transitive Property of Equality If 5*2 =10 and 7+3 =10 then 5*2 = 7+3. or if a=b and b=c then a=c
Transitive Property of Order If a >b and b >c then a >c
Substitution Property Given (7-3) +5= 4+5. or Given a =b, then b may be substituted for a.

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.
