# 1 Rational Numbers

### Rational Numbers

TermDefinition
algebraic expression a mathematical phrase that has at least one variable, and it can contain numbers and operation symbols
additive inverses Two numbers with the sum of zero
bar notation is used to indicate the digits that repeat in a repeating decimal. The numbers that lie underneath are the numbers that repeat.
non-terminating a decimal that continues on infinitely without ending in a sequence of zeros.
non-repeating a decimal that continues without terminating and without repeating a sequence of digits. They are not rational numbers.
repeating a decimal in which a digit, or a group of digits, repeat(s) infinitely. These are rational numbers.
terminating a decimal that has a finite number of digits, meaning that after a finite number of decimal places, all following decimal places have a value of 0. These are rational numbers.
commutative property CHANGE ORDER -for any numbers a and b, the product a x b is equal to the product b x a as well as the sum a +b = b+ a.
associative property CHANGE GROUPING - for any numbers x, y and z, the product (xy)z = x(yz) as well as the sum x + (y +z)= (x+y) +z.
distributive property MULTIPLY ACROSS PARENTHESES states that for any numbers a, b, and c, a(b + c) = ab + ac and a(b - c) = ab - ac.
rational numbers the set of numbers that can be written as a/b , where a and b are integers and b does not 0. All Fractions. Decimals that repeat or terminate. Integers. Whole and Natural numbers.
integer the set of whole numbers and their opposites {...-3, -1, 0, 3, 6...}
whole numbers the set of zero and counting numbers {0, 1, 2, 3, 4...}
natural numbers the set of counting numbers {1, 2, 3, 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:

• 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.
