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. 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






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






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






4. Same shape - but different size






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






6. A function whose graph is a straight line.






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






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






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






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






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






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






13. 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).






14. 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).






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






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






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






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






19. 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






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






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






22. 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






23. Statement that two fractions or ratios are equal






24. 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.






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






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






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






28. 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






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






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






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






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






33. Numeric value that does not change






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






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






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






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






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






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






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