Chapter 1- Mental Math Arithmetic- Getting Rid of the Calculator
Mental calculations use only thehuman mind in order to find a solution to a mathematical problem. The humanbrain is used as a calculation tool, and the end results are determined from amental computation of the arithmetic data itself. A calculator or computer isnot used to find the end result of the arithmetic problem.

Techniques
Various mental techniques arefrequently used to find a correct answer for a mental math calculation; thesemental math techniques usually take advantage of the decimal and numeralsystems. There are certain systems that may be used, and the method that ischosen is determined by the particular calculations that are being performed. Aradix may be used for easy tasks that simply use a decimal point location todecide the correct answer for a math problem. Multiplying and dividing by 10can be accurately done by moving the decimal point to the correct place withinthe numbers being used. A hexadecimal system needs to be used when the mathproblem uses other multiplying or dividing numbers. Using the number seven as amultiplier or divider may create a more complex mental math problem.
Techniques and Other Methods
There are other techniques andmethods that may be used to find the correct answers to mental math arithmeticproblems. The sum of the first nine digits of a group of nine numbers may beadded, and this group of nine digits is called an operand. This technique usesthe sum of the digits and several other operations to arrive at a correctanswer. This particular method is called casting out nines. This type of mentalmath calculation may be used after a certain number of practice sessions inorder to determine the correct sequence of operations needed.
Estimation and Mental MathArithmetic
A second method that is used formental math arithmetic is a technique called estimation. This type of mentalmath uses a necessary scaling of the numbers. This estimation will instruct themental math user to estimate the number of digits and to be aware of theexpected number of digits for the correct answer. Counting the number of digitsfor the final answer can assure the mental math processor that the answer iswithin an expected range and has the correct number of digits.
