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






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






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






4. 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.






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






6. The point where the x-axis and y-axis intersect on the coordinate plane; (0 - 0).






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






8. 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






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






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






11. 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






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






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






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






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






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






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






18. 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






19. 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






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






21. A function whose graph is a straight line.






22. 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






23. 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).






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






25. The smallest number - other than zero - that is a multiple of two or more given numbers; The LCM of 10 and 18 is 90.






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






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

29. (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.






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






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






32. 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.
