MATHEMATICS-SOME INTERESTING RESULT


25 x 92 = 2592

2178 x 4 = 8712
1089 x 9 = 9801

(20+25)2 = 2025
(30+25)2 = 3025
(98+01)2 = 9801
(88+209)2 = 88209
(494+209)2 = 494209
68 + 89 + 96 = 253
86 + 98 + 69 = 253

753 + 849 = 1602
847 + 359 = 1206
623 + 475 = 1098
789 + 246 = 1035
364 + 725 = 1089

13/4 + 13/9 = 169/36
13/4 x 13/9 = 169/36

3/5 - 3/8 = 9/40
3/5 x 3/8 = 9/40

169/30 + 13/15 = 13/2
169/30 ÷ 13/15 = 13/2

121/28 – 11/7 = 11/4
121/28 ÷ 11/7 = 11/4

2 + 2 = 4
2 x 2 = 4

1 + 2 + 3 = 6
1 x 2 x 3 = 6

Problem: 
Can you form “100” using all digits 1, 2, 3, 4, 5, 6, 7, 8 and 9 exactly once. Any mathematical symbols can be used. (There is no restriction in the number of symbols used)


Answer(s):
123 + 45 – 67 + 8 – 9 = 100
123 – 45 – 67 + 89 = 100
12 – 3 – 4 + 5 – 6 + 7 + 89 = 100
12 + 3 – 4 + 5 + 67 + 8 + 9 = 100

246 - (8 x 7) – 59 – 31 = 100
(9 x 4) + (6 x 3) + (8 x 7) - (5 x 2 x 1) = 100
√9 + 24 + 53 + 8 + 7 + 6 - 1 = 100
265 – 79 – 84 – 3 + 1 = 100
(1² x 8 x 9) + 67 – 35 - 4 = 100
1 x (9.8 + .2) x (4 – 3 + 7 - 6) x 5 = 100
(6 x 9) x (5 - 4) + 18/2 + 37 = 100
3² + (8 x 7) + (6 x 9) – 14 - 5 = 100

Beauty of Mathematics !!!

Some Tips are given below ....


1 x 8 + 1 = 9
12 x 8 + 2 = 98
123 x 8 + 3 = 987
1234 x 8 + 4 = 9876
12345 x 8 + 5 = 98765
123456 x 8 + 6 = 987654
1234567 x 8 + 7 = 9876543
12345678 x 8 + 8 = 98765432
123456789 x 8 + 9 = 987654321



1 x 9 + 2 = 11
12 x 9 + 3 = 111
123 x 9 + 4 = 1111
1234 x 9 + 5 = 11111
12345 x 9 + 6 = 111111
123456 x 9 + 7 = 1111111
1234567 x 9 + 8 = 11111111
12345678 x 9 + 9 = 111111111
123456789 x 9 +10= 1111111111


9 x 9 + 7 = 88
98 x 9 + 6 = 888
987 x 9 + 5 = 8888
9876 x 9 + 4 = 88888
98765 x 9 + 3 = 888888
987654 x 9 + 2 = 8888888
9876543 x 9 + 1 = 88888888
98765432 x 9 + 0 = 888888888

Brilliant, isn't it?

And look at this symmetry:

1 x 1 = 1
11 x 11 = 121
111 x 111 = 12321
1111 x 1111 = 1234321
11111 x 11111 = 123454321
111111 x 111111 = 12345654321
1111111 x 1111111 = 1234567654321
11111111 x 11111111 = 123456787654321
111111111 x 111111111 = 12345678987654321

Now, take a look at this...

101%

From a strictly mathematical viewpoint:

What Equals 100%?
What does it mean to give MORE than 100%?

Ever wonder about those people who say they are giving more than 100%?

We have all been in situations where someone wants you to
GIVE OVER 100%.

How about ACHIEVING 101%?

What equals 100% in life?

Here's a little mathematical formula that might help
answer these questions:

If:

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

Is represented as:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26.

If:

H-A-R-D-W-O- R- K

8+1+18+4+23+ 15+18+11 = 98%

And:

K-N-O-W-L-E- D-G-E

11+14+15+23+ 12+5+4+7+ 5 = 96%

But:

A-T-T-I-T-U- D-E

1+20+20+9+20+ 21+4+5 = 100%

THEN, look how far the love of God will take you:

L-O-V-E-O-F- G-O-D

12+15+22+5+15+ 6+7+15+4 = 101%

Therefore, one can conclude with mathematical certainty that:

While Hard Work and Knowledge will get you close, and Attitude will
get you there, It's the Love of God that will put you over the top!

It's up to you if you share this with your friends & loved ones just the way I did..
