Algebra Vocab: U. 1

Vocabulary List for Math Class Unit One

TermDefinition
Ratio two quantities, a comparison of two numbers, can be written as: # to #, # : #, or #/#
Variable an unknown, represented by a letter
Rates show up everywhere in the real world, ratios of two quantities, both of which are changing or varying
Expression a group or combination or numbers that we know and ones we don't (variables), does not have an equal sign
Order of Operations (PEMDAS) the "rules" for solving an expression, the order of steps you need to take to solve an expression, order: (parentheses, exponents, multiplication and division, addition and subtraction)
Commutative Property of Addition gives permission to rewrite addition problems in different orders than what are normally given, changes the order of the numbers without changing the sum
Commutative Property of Multiplication gives permission to rewrite multiplication problems in different orders than what are normally given, changes the order of the numbers without changing the product
Associative Property of Addition gives permission to rewrite addition problems in different orders than what are normally given, changing the location of the parentheses around numbers without changing the sum
Associative Property of Multiplication gives permission to rewrite multiplication problems in different orders than what are normally given, changing the location of the parentheses around numbers without changing the product
Evaluating Expressions finding the results of the calculations of an expression when all variable values are known
Binomial an expression with two terms
Equivalent Expressions two (or more) algebraic expressions that have the same value for every value of the substitution variable (or variables); no matter what value you stick in for x (or y or z) the two expressions come out equal
Factoring Expressions the process of writing an equivalent expression as purely the product of other expressions
Distributive Property of Addition over Multiplication gives permission to rewrite multiplication problems in different orders than what are normally given; if a, b, and c all represent real numbers then: a (b + c) = a x b + a x c; applying a multiplication to all parts of a sum
Distributive Property of Addition over Division gives permission to rewrite division problems in different orders than what are normally given; if a, b, and c all represent real numbers then: b + c / a = b / a + c / a; applying a division to all parts of a sum
Trinomial an expression with three terms

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.
