4 Tips For Doing Fast Math

Most of the people find it one of the hardest job to do the math and as it is the vital element in today’s life, then it is highly difficult for most of the people to remember the small equations. Therefore, it is recommended that you must use the following tricks and tips to do the match effectively and quickly in your mind without using the online graphic calculator. Let’s have a look at all these tips.

1. Trick To Divide:
Here are some of the quickest and effective ways when you can divide a number evenly with these certain numbers. Have a look at all these tricks:
You must divide by ten if the number is ending with 0
You must divide by 9 when you add the digits, and their total is equally divisible by 9
You must divide by eight if the last three digits are 000 or they are divisible by 8
You must divide by six if you have an even number and when the two digits are added together, and their answer is evenly divisible by 3
You must divide by 5 when the end is 5 or 0
You must divide by four if the end number is 00 and the two number digit is divisible evenly by 4
You must divide by three if the two digits are added together and their result is evenly divisible by 3
You must divide by two if the digit ends with 0, 2, 4, 6, 8

2. Multiply by 9:
This method is highly useful when you multiply every number that you want to simplify with 9. Lets see how it works.
Take the example of 9 * 3
Step 1 is the subtracting fraction one that must be subtracted from the number that is 3 – 1 = 2
Step 2: subtract the number at the end from 9
9 – 2 = 7
So your answer will be 27. The two from the step 1 and seven from the step 2.

Step 2: now divide the 23.5 by 2, and you will get 11.75, and this is the actual answer to your question.

4. Multiply Number That Ends In Zero:
Multiplication of the number that is ending with 0 is a highly simple task. Such as, you will multiply all the numbers, then add zero at the end.
300 * 400
Firstly, multiply 3 * 4 = 12, now put all the zeros that are 12,0000.
