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. Same shape - but different size






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






3. 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






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






5. 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






6. 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






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






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






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






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






11. 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






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






13. A function whose graph is a straight line.






14. 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






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






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






17. Numeric value that does not change






18. (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.






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






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






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






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






23. Statement that two fractions or ratios are equal






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






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






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






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






28. The reciprocal of a number.






29. Same shape - but different size






30. The reciprocal of a number.






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






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






33. 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).






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






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






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






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






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






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






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






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