Whole Numbers : a whole number is a nonnegative number that is not expressed as a fraction or a decimal. Integers : whole number or its opposite ( a number line can be used to demonstrate the value of an integer). Adding integers : adding numbers with the same sign result in a sum of the same sign. (positive)+(positive)= positive (negative)+(negative)= negative multiplying and adding integers : positive x positive = positive positive X negative = negative negative x positive = neg...

Integers Positive and Negative Whole Numbers; Includes 0 Prime Number A whole number greater than 1 that only has two factors (itself and 1) Composite Number A whole number greater than 1 that has more than two different factors Rational Numbers All integers, decimals and fractions; any terminating or repeating decimal number Irrational Numbers Cannot be written as fractions or decimals because the number of decimal places is infinite and there is no recurring pattern of digits within ...

"base 10" and base system -any number times 10,100,1000.... you multiply the first digit by that number then add those amount of zeros to the end of the number (ie. 375 x100=37500) -any number divided by 10,100,1000... you divide the first digit by that number then move the decimal to the left according to the amount of zeroes (ie. 375/1000= .375) --this is done with any cardinal numbers A cardinal number tells "how many." Cardinal numbers are also known as "counting numbers," b...

Commutative Property : the result of an arithmetic operation is not affected by reversing the order of the numbers. addition and multiplication are operations that can be done with the commutative property. Example: 5X2=2X5 Associative Property : When the parentheses can be moved to group different numbers in an arithmetic problem together without changing the result. addition and multiplication are associative properties. Example: 2+(3+4)= (2+3)+4 or 2(ab)=(2a)b Distributive Pr...

Math Praxis Practice Test (5003) Questions and Answers Already Passed Six children have collected these amounts in their piggy banks: $10, $33, $45, $23, $1, and $68. What is the median of their savings? a. $28 b. $33 c. $23 d. $66 answer: a. $28 Rearrange the numbers in increasing order: 1, 10, 23, 33, 45, and 68. The median of a sequence of numbers is the middle value. Since there are six numbers, there are two values in the middle 23 and 33 and, therefore, the median is the average of ...

Math Praxis Practice Test (5003) Questions and Answers 3. Which of the following expressions is equivalent to the expression 21−6x for all values of x ? 5−2(8−3x) 6+3(5−2x) 25−(4−6x) 3(4−2x)−9 7(3−2x)−8x 6+3(5−2x) Option (B) is correct. Using the distributive property, 6+3(5−2x)=6+15−6x=21−6x. None of the other selections is equivalent to this. 5. A right circular cylinder with base B is shown. If a plane that is neither parallel nor perpendicular to b...
