Algebra definitions

TermDefinition
Algebraic Expressions Algebraic expressions have at least one variable and one operation.
Variables Variable is a letter that represents an unknown value (varies); can use any letter.
Constants Constant is a term without a variable; numbers.
Coefficients Coefficient is the number part of a term without variables.
Terms A term is either a single number or variable, or numbers and variables multiplied together. Terms are usually separated by addition and subtraction signs.
Like Terms Two or more terms with the same variable or exponent are called like terms.
Sum answer to a addition problem
difference answer to a subtraction problem
product answer to a multiplication problem
quotient answer to a division problem
fewer than/less than Equal subtract and reverse
How much more or how much less Equal subtraction
percent or fraction of Equal multiply
each Equal divide
than/from mean to reverse the order
Associative Property In the way in which numbers are grouped when added or multiplied does not change the answer.
Commutative Property The order in which numbers are added or multiplied does not change the answer.
Identity Property of Addition The sum of an addend and 0 is the same as the addend.
Identity Property of Multiplication The product of any factor and 1 is the same as the factor
Additive Inverse Property Adding a number and its opposite will produce a sum of zero
Multiplicative Inverse Property Multiplying any number and its inverse equals one.
Associative Property (x+7)+9=x+(7+9)
Associative Property 4(3x9)=(4x3)9
Commutative Property (x+7)+9=(+(7+x)
Commutative Property 5x6=6x5
Identity Property of Addition x+0=x
Identity Property of Multiplication 6(1)=6
Multiplicative Inverse Property 4x1/4=1
Additive Inverse Property -5+5=0
Distributive Property 4(x+3)=4x+12
Distributive Property 16+40=8(2+5)

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.
