C784 Exam Questions with All Correct Answers

C784 Exam Questions with All Correct Answers rational number - Answer-A number that can be written as a ratio of integers, which means it can be written as a fraction. product - Answer-The result of multiplying values. whole number - Answer-A number whose value is 0 or greater and can be represented without a fractional or a decimal component. identity property - Answer-The property that 0 can be added to any number without changing the value of the number. Likewise, 1 can be multiplied by any number without changing the value of that number. associative property - Answer-The property that under certain operations in a multi-step expression, the computations may be done in any order. Commonly represented as (a + b) + c = a + (b + c). Addition and multiplication both have this property, but subtraction and division do not. perfect square - Answer-The product of any integer with itself yields this. So, a number is this if it can be written as the square of an integer. For example, 9 is this because 3 * 3 = 9.

Addition and multiplication have this property: a + b = b + a and ab = ba. radical sign - Answer-The symbol which indicates to take the square root of the number that follows. additive inverse - Answer-Two numbers equidistant from 0 on a number line whose sum is 0. For example, 3 and -3. greatest common factor (GCF) - Answer-The greatest number that is both a factor of a and a factor of b. factor tree - Answer-A graphical method used to identify the prime factorization of an integer. integer - Answer-A number, (positive, negative, or zero), that can be represented without a fractional or a decimal component.
