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






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






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






4. The reciprocal of a number.






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






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






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






8. Same shape - but different size






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






10. Numeric value that does not change






11. 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






12. The reciprocal of a number.






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






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






15. 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






16. (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.






17. 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)






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






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






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






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






22. Statement that two fractions or ratios are equal






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






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






25. Numeric value that does not change






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






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






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






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






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






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






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






33. 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






34. 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)






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






36. 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






37. 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.






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






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