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. Math phrase that uses variables - numbers and operation symbols






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






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






4. Statement that two fractions or ratios are equal






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






6. 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






7. A decimal in which one or more digits repeat infinitely; The repeating portion of the decimal is shown with a short line drawn over the repeating numbers.






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






9. Same shape - but different size






10. 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.






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 (denominator cannot be zero)






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






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






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






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






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






18. 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






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






20. 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






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






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






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






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






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






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






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






29. A function whose graph is a straight line.






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






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






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






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






34. Numeric value that does not change






35. 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






36. A quantity that does not vary






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






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






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