  • 1. How to Simplify MathProblems?
  • 2. The secret to acquiring all these benefits has its basis inlearning simple strategies for mental maths. Most of themseek to address the 4 basic areas of mathematicalcomputation. Visit maths problems to read more about it.Here are some samples from each of the four categories:
  • 3. MultiplicationMultiplying double digit numbers is rather difficult to domentally. If one of these numbers is 11, take the other numberand separate its two figures (36X11=3_6). Get the value oftheir sum (3+6=9) and place it in this middle space (396). Thenew number is your answer.A challenge arises when the sum of the two values is a doubledigit number (93X11=9_3). In such a case, place the seconddigit in that middle position (923); add the first digit to thenumber in first position (1023).
  • 4. AdditionBasic additions are rarely a challenge but if one has to addnumbers in a series, it often becomes an uphill climb. An easytrick for getting the sum of any 10-number series is bycomputing the product of its 7th number and 11. This is aneasy calculation when one employs the shortcut formultiplication of numbers by 11.
  • 5. SubtractionGetting the difference between big numbers is a tough mentalmaths challenge. For instance, a question may require you tosubtract a number from 1000 (1000-732). The easiest way isto subtract the first two digits from 9, (9-7=2 and 9-3=6).Subtract the last digit from 10 (10-2=8) and combine thethree digits to get the final answer (268).
  • 6. DivisionThere is an easy technique for dividing large numbers by 5.Simply multiply the number by 2 (13982x2=27964) and thenplace a decimal point between the last two digits and youhave your answer (2796.4).These are just a sample of the numerous shortcuts that onecan use to make mathematics easier. By using internetreferences prepared for this purpose, one can get a lot moreof this sort. They make it easier to compute math problemsmentally than using a calculator.
  • 7. The use of these and other similar strategies has proved veryuseful for persons having to sit for aptitude tests. They alsohelp in saving time during examinations. Take your timetoresearch additional mental maths strategies and enjoy theseand numerous other benefits.http://brilliant.org/
