Easily solve all Math problems.
Here at the tips and tricks that every student must do in his mind to get the results, whether there is adding fraction or the dividing fraction, it doesn’t make a difference at all. After these tips, you will be able to do all the things.
As these numbers are difficult to calculate in mind. So you can round these numbers, and this will make it more manageable. Such as if you make 288 to 290 and 344 to 350. Now add the 290 to 350 and the total will be 640.
Now to get the exact answer of the values that we used, you must remember the numbers that you used and subtracted the number from the original value. For examples:
290-288 = 2 and 350-344 = 6
Now add the two numbers, i.e. 2 + 6 = 8.
If you want to get the exact answer, you have to subtract this 8 from the combined value that is 640 and the actual answer will be:
640 – 8 = 632
So, the exact answer is 632.
When you are multiplying five by an odd number. this 8 from the combined value that is 640 and the actual answer will be:
Such as 5 *3
