    You must have heard about mental math- the ability to do calculations swiftly and effectively in one's head- and how vital it is for every individual to get the hang of it. But, why is it important?

    In the words of eminent math homework help stalwarts, doing certain math calculations help you save time, sharpens your brain, enhance math skills and help to excel in advanced courses. Here, we have enlisted unique fast math strategies you need to master for the long run.

     

    1. Addition of Large Numbers

    Adding large numbers within a few minutes can be hugely daunting, which leads you to seek math homework paper help services. You can simplify this process by making all the numbers a multiple of 10.

    Example- 544+338

    Rounding these numbers will make them much more manageable. Thus, 554 becomes 550, and 338 becomes 340. Add 550 and 340. The total is 890.

    Now, 550-544=6 and 340-338=2.

    Add 2 and 6 to get a total of 8. Then, subtract 8 from 890.

    890-8=882.

    Thus, the answer is 882.

     

     

     

    1. Doubles +1

    If you go through popular forums of academic math experts of the US, then you must know it is wise to encourage children to memorize the doubles from 1+1 through 9+9. After this, many other additional facts will be at their fingertips, like the ones we can term 'double plus one more.'

    Like, 6+7 is just one more than 6+6, or 9+9 is just one more than 9+8.

     

    1. Five Times A Number

    To find the value of 5 times of any number, you need to multiply first that number times 10 and then take half of that. For instance, 5*28 can be found by multiplying 10*28= 280 and taking half of the result, which gives 140.

     

    1. Conversion of Temperatures

    If you aim to convert Celsius to Fahrenheit roughly, you need to multiply it by 2. Then, add 30. Again, if you need to convert Fahrenheit to Celsius, subtract 30 and divide by 2.

     

    1. Percentage

    Mark Richardson, an eminent stalwart of the US, who often cater to ‘do my math homework requests, asserts that finding a percentage of a number can be tricky. However, it becomes much easier to understand when you tend to think about it in the correct terms. Like, to find out what 5% of 225 is, follow this method-

    • Move the decimal point over by one place; 225 becomes 22.5.
    • Divide 22.5 by the number 2. The answer is 11.25. This is also the answer to the original equation.
