How do you evaluate #55+57+58+61+63#?
The answer to
The way we are going to evaluate this problem is going to be like, add first 2 numbers and add the answer to that to the next number and so on. Kind of like a pattern! I hope that makes sense, but if it doesn't, I hope you'll get it soon! :)
OK, now let's start!
You keep doing that till you are finished with all of your numbers!
There you go! The answer is 294 and I hope that you now understood the "pattern" that I used instead of adding all of them together at the same time! I hope that this answer helps you! :)
My source is my mind!
The answer is
Disclaimer: A bit different technique is used below.
My technique is:
As you can see that all the terms in the given problem are near or equal to
So I say that just multiply the number
Now calculate every term is how much greater than
You see that;
#55 - 55 = 0#
#57 - 55 = 2#
#58 - 55 = 3#
#61 - 55 = 6#
#63 - 55 = 8#
Now just simply add the sum of these differences to the product of
This is the answer.
This procedure might look complicated but is a matter of seconds when you actually think about it.
