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 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).






2. 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






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






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






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






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






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






8. The reciprocal of a number.






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






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






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






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






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






14. The distance from zero to the real number on a number line.






15. Statement that two fractions or ratios are equal






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






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






18. Numeric value that does not change






19. A function whose graph is a straight line.






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






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






22. (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.






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






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






25. 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






26. A quantity that does not vary






27. Statement that two fractions or ratios are equal






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






29. 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






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






31. A pair of numbers that can be used to locate a point on a coordinate plane.






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






33. 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.






34. The reciprocal of a number.






35. A quantity that does not vary






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






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






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






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






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






42. Letter that represents a number; variable amounts may change






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