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






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






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






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






6. 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).






7. A function whose graph is a straight line.






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






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






10. Statement that two fractions or ratios are equal






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






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






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






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






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






16. 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






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






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






19. 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)






20. The reciprocal of a number.






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






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






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






24. 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)






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






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






27. Specific form of representing ratios - examples - a to b or 2 to 3






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






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






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






31. 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






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






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






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






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






36. 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
