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...

Math Praxis Practice Test (5003) (Answered 100% Correctly, Well Elaborated) 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 t...

"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...
