Math Basic Skills Exam-Questions and Answers Graded A+ distribute - ANSWER-To rewrite the product of the number and a sum or difference using the distributive property. distributive property of multiplication over addition - ANSWER-The product of a number and a sum is the same as the sum of the product of the number and each of the addends making up the sum. For example, 3(4 + 2) = 3(4) + 3(2). distributive property of multiplication over subtraction - ANSWER-The product of a number and a difference is the same as the difference of the product of the number and each of the numbers being subtracted. For example, 8(10 - 2) = 8(10) - 8(2). addend - ANSWER-A number added to one or more numbers to form a sum. addition property of 0 - ANSWER-The sum of any number and 0 is equal to that number. The number 0 is often called the additive identity. amount - ANSWER-In a percent problem, the portion of the whole corresponding to the percent. associative law of addition - ANSWER-For three or more numbers, the sum is the same regardless of how you group the numbers. For example, (6 + 2) + 1 = 6 + (2 + 1). associative law of multiplication - ANSWER-For three or more numbers, the product is the same regardless of how you group the numbers. For example, 3 • (5 • 7) = 3 • (5 • 7). base - ANSWER-In a percent problem, the base represents how much should be considered 100% (the whole); in exponents, the base is the value that is raised to a power when a number is written in exponential notation.

For example, 6 + 4 = 4 + 6. commutative law of multiplication - ANSWER-Two numbers can be multiplied in any order without changing the product. For example, 8 • 9 = 9 • 8. composite number - ANSWER-A natural number that has at least one factor other than 1 and itself. cubing - ANSWER- Raising a number to a power of 3. 23 is read "2 to the third power" or "2 cubed," and means use 2 as a factor three times in the multiplication. 23 = 2 • 2 • 2 = 8. - ANSWER- cup - ANSWER-A unit of capacity equal to 8 fluid ounces.
