Several mental math addition techniques are available in both Mental Math Unleash The Power eBooks. This particular technique is used for adding two numbers to each other without carrying a value over as in standard math. It is based on adding one of the numbers to the other number which is simplified or broken down into smaller parts one part at a time. The logic here is that adding smaller parts is generally easier than adding whole parts, simplifying the math addition process. Depending on the size of the numbers and how they are arranged internally, larger numbers usually mean there are more parts.
This is mental math technique is for subtracting between two numbers. It is one of the several techniques available in the Mental Math Unleash The Power eBook. Subtraction is made easier by using base amounts where possible along with the fact that borrowing is never required. The mental math subtraction technique here uses smaller parts of the number being subtracted for subtracting it from another. Similar principles are also applied in several other math subjects for mental computations such as addition, multiplication, division, squares, and etc.
Once again, there are many mental math techniques for multiplying various kinds of numbers. This technique focuses on multiplying any whole two-digit numbers together using the crosswise method, which resembles the standard math method except it is performed mentally. The great part is that each multiplication process consists of only multiplying two single digits together making it very manageable. For small numbers such as two and three-digit numbers, other methods are recommended this technique is more efficient and manageable than others when multiplying large numbers to each other.
This is one of many mental math techniques for multiplying three-digit numbers together in your head without the use of pencil and paper or any electronic devices based on the crosswise method. The methodology is similar to the technique on the immediate left for multiplying two-digit numbers to each other. Keep in mind, use the proper technique in the right situations for the best efficiency since some techniques are more manageable than others for performing the same tasks. In terms of how this technique is applied, it is closely related to multiplying three-digit numbers together in standard math.
This is a very specific technique for multiplying two-digit numbers to each other – these numbers have values close to and under 100.
(98 X 95) or (99 X 85) or (92 X 96), etc.
The technique, based on two parts, is more efficient and manageable for multiplying these types of two-digit numbers to each other than other methods. Solving the answers involving these types of numbers with this technique is easy.
This is another specific technique for multiplying two-digit numbers to each other – these numbers have values close to and over 100. The technique is not recommended if the numbers are too far from 100 such as 124, 134, or beyond.
(102 X 107) or (112 X 106) or (108 X 104), etc.
The numbers in each set above are close and over 100. For these types of numbers, this technique is preferred over others for performing the same task.
This mental math technique is specifically designed for multiplying two numbers that end in a 5 each – meaning they both end in 5 and have the same value. Other closely related techniques are also available in the Mental Math Unleash The Power eBook.
(25 X 25) or (35 X 35) or (115 X 115), etc.
It is easy to learn and apply. Here are two conditions that need to be met for this technique to be applicable.
(i) Both numbers have the same value.
(ii) Both numbers end in a 5.
(i) Both numbers have the same value.
(ii) Both numbers end in a 5.
This is a great mental math technique for multiplying any whole numbers by 5 in your head. Once you become are proficient enough, the technique can be expanded to multiplying decimal numbers as well. Therefore, it is not limited to only to certain types of numbers but a whole range of them.
However, answers can be solved even faster if the numbers meet certain requirements such as in the following numbers.
(324 X 5) or (46.14 X 5) or (802246 X 5)
The mental math technique here is used for dividing numbers by 5 quickly. It can also be used for dividing decimal numbers by 5 but being proficient in dividing whole numbers by 5 first is important. This technique uses a multiplication process instead of division when dividing by 5.
(124 ÷ 5) or (781 ÷ 5) or (67248 ÷ 5)
Math division is considered by most to be one of the hardest fundamental math courses – this makes it easier.
As stated before, many mental math techniques are available for solving math problems and typically there is more than one technique that can perform the same task. Here is an extremely effective division technique for dividing a number by another very efficient and manageable under the right conditions.
(246 ÷ 2) or (1201 ÷ 5) or (511734 ÷ 17)
When the right situations exist, the answers can be solved within in seconds – even faster than using pen/pencil and paper.
This mental math technique is for dividing one number by another using the dividend but based on the divisor. Under the right situations, the answers can be computed quickly regardless of the size of the dividends.
This is one of those techniques designed specifically for dividing for when the divisor and dividend share a special relationship. The relation is based on parts of the dividend where one part is evenly divisible by the divisor. A compensation step is required but it is relatively easy to perform.

This is the first mental math trick or technique for squaring any two-digit numbers in the Mental Math Unleash The Power eBook. It can be used in a number of different ways, and one way is depicted in the video.
The technique consists of simple math addition and multiplication procedures versus the standard approach, which involves multiplying an identical two-digit number together and then completing the arithmetic. Squaring a two-digit number such as 32 means to multiply 32 by 32.
The technique consists of simple math addition and multiplication procedures versus the standard approach, which involves multiplying an identical two-digit number together and then completing the arithmetic. Squaring a two-digit number such as 32 means to multiply 32 by 32.
This technique can be mastered after working one or two examples, and is probably the easiest technique for squaring numbers with just 1s such as 111, 1111, 11111, and so forth. Squaring a number means to multiply the number to itself. For example, squaring 1111 means to multiply 1111 by 1111. By standard math methodologies, multiplication is performed and starts from right to left one digit of the bottom (or right) number at a time.
So how would you square numbers with only 1s? Multiplication is not even necessary using this technique.

This mental math technique shows us how to estimate the square roots of two-digit non-perfect square numbers. What is a non-perfect square number?. Basically, a non-perfect square number is made from multiplying a decimal number to itself.
For example, to find the square root of 1.4641 is to determine a decimal number when multiplied to itself gives 1.4641 (rounded). So this means the decimal number that was multiplied to itself is the square root of 1.4641 because it requires multiplying the decimal number to itself in producing 1.4641.

Cubing numbers mentally may seem intimidating but with the help of the mental math resources from www.abellna.com, these types of computations can be performed efficiently. Cubing two and three-digit numbers is generally one of the most challenging mental computations to perform – several techniques for cubing numbers are included in both eBooks. General as well as specific techniques are available. For example, a general technique can be used for cubing two-digit numbers such as 11 or 74 but using a specific one for cubing numbers like 11 can do the task more efficiently and faster.
Can you find the cube root for a number such as 12167 in your head quickly? Watch this video if you do. The mental math cube root technique here is for determining the cube roots of five-digit perfect cube numbers (others are also available in the eBook).
21 cubed = 21 X 21 X 21
Perfect cube numbers are created from multiplying three of the same whole numbers to each other. With proficiency in this technique, the answers can be found without the use of pen/pencil and paper.
This technique teaches how to add two fractions quickly mentally without having to find the lowest common denominator (LCD) and applying other math processes. Plenty of mental math fraction techniques are available for adding, subtracting, multiplying, and dividing fractions in both eBooks.
Generally, when adding two fractions to each other the lowest common denominator (LCD) is required before other arithmetic processes can be used in finding the answer. Using the technique here does not require the LCD.
