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






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






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






4. 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.






5. Changing the grouping of terms will not change the sum - (a + b) + c = a + (b + c); ex: (5+3) + 1 = 5 + (3 + 1)






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






7. 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).






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






9. 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.






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






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






12. 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






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






14. 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).






15. (mathematics) one of a pair of numbers whose sum is zero






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






17. 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.






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






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






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






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






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






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






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






25. Changing the grouping of terms will not change the sum - (a + b) + c = a + (b + c); ex: (5+3) + 1 = 5 + (3 + 1)






26. 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






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






28. Statement that two fractions or ratios are equal






29. 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






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






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






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






33. (mathematics) one of a pair of numbers whose product is 1: the reciprocal of 2/3 is 3/2; a fraction that has been flipped. The reciprocal of 3/4 is 4/3.






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






35. 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.
