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






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






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






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






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






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






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






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






10. The reciprocal of a number.






11. (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.






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






13. (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.






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






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






16. 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






17. Statement that two fractions or ratios are equal






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






19. A quantity that does not vary






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






21. Numeric value that does not change






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






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






24. 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).






25. 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.






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






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






28. 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






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






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






31. 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)






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






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






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






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






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






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






38. 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






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






40. 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
