Middle Grade Math And Basic Algebra

Subjects : math, algebra
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A number that can be written as a/b where a and b are integers - but b is not equal to 0; an integer or a fraction; examples: 6 can be expressed as 6/1; 0.5 can be expressed as 1/2.






2. Numeric value that does not change






3. Math phrase that uses variables - numbers and operation symbols






4. A comparison of two quantities - may be directly represented by numbers and or variables






5. A number multiplied by a variable in an algebraic expression; a constant number that serves as a measure of some property or characteristic






6. Same shape - but different size






7. For any number a and b - a + b = b + a






8. For any number a and b - a + b = b + a






9. A quantity obtained by multiplication; the answer to a multiplication problem






10. An expression that contains only numbers and operations (2 3) + 1






11. The product of a quantity by an integer; example 24 is a multiple of 3 and 8






12. A property indicating a special way in Which multiplication is applied to addition of two or more numbers in which each term inside a set of parentheses can be multiplied by a factor outside the parentheses - such as a(b + c) = ab + ac; ex: 4(3 + 8)






13. A symbol (like x or y) that is used in mathematical or logical expressions to represent a variable quantity; in the expression 2x + 3 - x is the variable






14. The Zero Property of Addition. Adding 0 to a number leaves it unchanged; ex: 67+0=67 - 67+0=67






15. An expression that contains only numbers and operations (2 3) + 1






16. The number obtained by division; the ratio of two quantities to be divided; the answer to a division problem






17. Any of the numbers (or symbols) that form a product when multiplied together; 3 is a factor of 9






18. A quantity that does not vary






19. Specific form of representing ratios - examples - a to b or 2 to 3






20. The reciprocal of a number.






21. The largest common factor of two or more given numbers; The GCF of 27 and 45 is 9.






22. The x- and y-axes divide the coordinate plane into four regions. Each region is called a quadrant.






23. An input-output relationship that has exactly one output for each input; An equation written with two variables where only one output exists for each input; example: y = 2x +1






24. Any of the natural numbers (positive or negative) or zero; any of the set of whole numbers and their opposites






25. The x- and y-axes divide the coordinate plane into four regions. Each region is called a quadrant.






26. Numeric value that does not change






27. The ratio between the size of something and a representation of it






28. All rational or irrational numbers; real numbers can be represented on the real number line






29. States that changing grouping of factors does not change the product. (ab)c = a(bc); ex: (2 6) 7 = 2 (6 7)






30. An equation whose solutions form a straight line on a coordinate plane; example: y = 3x - 1






31. The reciprocal of a number.






32. A number written as the product of its prime factors; examples: 10 = 2 5 - 24 = 2^3 3 (^3 means the 3 is written smaller and to the upper right of 2).






33. The operation which undoes an operation - the opposite operation: subtraction is the inverse of addition - addition is the inverse of subtraction; division is the inverse of multiplication - multiplication is the inverse of division - square root is






34. The order in which operations in an expression to be evaluated are carried out. 1. parentheses 2. exponets 3. multiplication and divison 4. addition and subtraction






35. A mathematical phrase involving one or more terms and operations






36. A decimal in which one or more digits repeat infinitely; The repeating portion of the decimal is shown with a short line drawn over the repeating numbers.






37. The operation which undoes an operation - the opposite operation: subtraction is the inverse of addition - addition is the inverse of subtraction; division is the inverse of multiplication - multiplication is the inverse of division - square root is
