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. Changing the order of the factors does not change the product; for example 10 x 9 = 9 x 10; a b = b a






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






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






4. A real number that cannot be expressed as a rational number






5. The ratio of dimensions of the new image to those of the original figure






6. The number that indicates how many times the base is used as a factor






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






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






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






10. A diagram of an object in which the dimensions are in proportion to the actual dimensions of the object.






11. A method of measurement that uses formulas - similar figures - and/or proportions.






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






13. Specific form of representing ratios - examples - a:b or 2:3






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






15. 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






16. A real number that cannot be expressed as a rational number






17. A fraction in which the numerator is greater than or equal to the denominator; examples: 5/5 or 7/4






18. Specific form of representing ratios - examples - a/b or 2/3 (denominator cannot be zero)






19. An ordered list or numbers; example: 2 -4 -6 -8 -10...






20. 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)






21. Changing the order of the factors does not change the product; for example 10 x 9 = 9 x 10; a b = b a






22. Fractions that name the same amount or part - 1/2 and 2/4 are equivalent fractions






23. A quantity that does not vary






24. Expressions that contain the same variables to the same power






25. 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






26. A quantity that does not vary






27. 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






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






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






30. Same shape - but different size






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






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






33. Expressions that contain the same variables to the same power






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






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






36. 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.






37. The plane formed by 2 number lines that intersect at their zero points dividing the plane into 4 quadrants; A coordinate system formed by the intersection of a horizontal number line - called the x-axis - and a vertical number line - called the y-axi






38. Statement that two fractions or ratios are equal






39. A decimal number that ends or terminates; example: 6.75






40. 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.

43. An ordered list or numbers; example: 2 -4 -6 -8 -10...






44. 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).
