# Math Monday

Brian has scores of 88, 95 on his first two math tests, he wants to have an average score at least 90 points.

There are total three tests, what score must Brian get on his third test to have an overall average of 90?

Hint:

Test 1:      88

Test 2:      95

Test 3:     ___

____________

270

Analysis: To achieve an average of 90 in three tests, Brian needs to

have total score 90+90+90=270, he already has two scores,

thus it is up to YOU to figure out what Brian must score in

test 3  to reach his goal?

Solution : 87.

Good Luck!

If YOU have a moment, please answer this simple question:

Take a piece of paper from your computer printer, 8.5*11 in size, you agree that there are four (4) corners for the paper which is rectangle shape, now take a scissor and cut one (1) corner off the paper by straight line (only once for each result), how many corners left on the remain paper?

Very easy if you actually do it!

Only a tiny trick in it, Good Luck!

Happy Saturday Evening!  :)

PS: You can also fold it for one time to get a result, there are two solutions,

If you divide the rectangle into exactly two equal pieces of triangular paper, then you get 4-1=3, 3 corners,

But if you cut out one corner and get two pieces of paper, with a small triangle removed, you get 4-2=5 corners,amazing math humor, isn’t it?

Good job, everyone, everyone got 5 corners, the other case is a trick, as I mentioned…;)

# Magical Number Nine (9) On Math Monday

Wow, It is Monday.  I decide to make Mondays Math Monday!

I miss Math, let’s discover the magic in number nine (9).

As you do “Times Table By 9″ , you may notice that the digits always add up to “9″…

Let’s check it out:

1*9=9  –>0+9=9

2*9=18  –>1+8=9

3*9=27  –>2+7=9

4*9=36  –>3+6=9

5*9=45  –>4+5=9

6*9=54  –>5+4=9

7*9=63  –>6+3=9

8*9=72  –>7+2=9

9*9=81  –>8+1=9

10*9=90  –>9+0=9

Isn’t this number game FUN?

Does it work for larger numbers? You may wonder.

Yes, this works for any number multiples 9….

Say: 11*9=99  –>9+9=18  –>1+8=9

100*9=900  –>9+0+0=9

211*9=1899  –>1+8+9+9=27  –>2+7=9

1005*9=9045  –>9+0+4+5=18  –>1=8=9

42001*9=378,009  –>3+7+8+0+0+9=27  –>2+7=9

Amazing math facts! :).  I hope that YOU have FUN learning and discovering the magical number nine (9) on Math Monday.

If interested, please do an example to confirm this fact above:

___ *9=_____,  –>___+___=____,

Thank YOU for sharing the wisdom of magical numbers in nine (9).  Happy Math Monday to YOU All!

Happy Martin Luther King’s Day to You all Who Celebrate This Special Day!

# Count From 1 To 10 Twenty different Ways (1-5)

Counting from 1 to 10 is very important to children’  initial learning about mathematical concepts. Recall on Barney And Friends of PBS , they count from 1 to 10 with two numbers connected at a time.  I revised the WORDINGS and share the first five (5) different ways of doing it, enjoy!

—————————————————————————————————————————————————

I:

1, 2, go to the zoo,

3, 4, shop at the store,

5, 6, build with bricks,

7, 8, sugar is sweet.

9, 10, buy me a pen.

II:

1, 2, Winnie the pooh,

3, 4, eat with a paw,

5, 6, search for beehives,

7, 8, honey tastes great,

9, 10, hungry again.

III:

1, 2, an owl says hoot,

3, 4, tigers roar,

5, 6, a fox hides in a box,

7, 8, a bird says tweet,

9, 10, stay in the den.

IV:

1, 2, cows say moo,

3, 4, two walls make a hall,

5, 6, chew the grass,

7, 8, breed in high rate,

9, 10, big fat hen.

V:

1, 2, ghosts say boo,

3, 4, stop the snore,

5, 6, do more tricks,

7, 8, juggle one more plate,

9, 10, birds love to sing.

————————————————————————————————————————————————–

Today’s Question for YOU:

How do you teach your kids to count? If you have no children yet, how did you learn about numbers when you were young? Do you enjoy counting at all?

Thank YOU for the time, Happy Monday!

# Solve A Math Problem!

Hello, how are you?

If you are interested in math, this problem is for you to work on and solve.

Start with 3,

Add 2,

Then multiple by 102,

Then divide by 5,

Then add 800,

Then subtract by 14,

What do you get?

_____
Please use two (2) words only to describe it.

Thank you in advance, have FUN.

PS:correct answer in number is 888, I required you to say it using two words, all entries are well done.

Other possible way to say it:

triple 8′s,

triple eight,

triple A’s

sounds great :).

Thank you all for the number FUN.

# Complex Numbers

When it comes to complex numbers,

You may notice a strange guy,

Who and Why?

That guy is the imaginary number i.

Look at how i divides a pie

Into 4 pieces, as i, -1, -i, 1,

And i is i,

i squared is negative one, -1,

i cubed is opposite of i, -i,

i fourth is positive one, 1.

If you want to go further with the power of i,

You know i fifth is the same as i,

Because 5 is 4+1,

And i fourth power goes back to 1.

Thus the power of i is easy to simplify.

To learn more,

Divide any power of i by four, 4.

Complex solutions always come in pairs,

a+bi, a-bi are conjugate pairs.

Addition, Subtraction,

Multiplication, and Division,

All work the same wonders

In complex numbers

As they do in real numbers.

Make sure real parts go with real parts,

Imaginary parts join imaginary parts.

The final expression will always be  a+bi,

With a, b either a whole number or a fraction.

If b is a fraction,

Make sure i sits on top,

Otherwise,

Make 1 over i equal to negative i, -i.

Do you understand the function of i?

I like i,

Please don’t ask me why!

# See How Math Is Employed In Words With Its Worth!

Suppose A stands for 1%, B represents 2%, and continue like this, we have ….X implies 24%, Y means 25%, and Z is 26%.

Thus, we have this mathematical formula to work on and with trying to view how we live our lives in order to get a perfect score, 100%.

Let

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

be indexed by numbers in percentage 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

Now, we have

R-A-G-E-F-R-E-E

18+1+7+5+6+18+5=5=65—> 65%

And

D-I-L-L-I-G-E-N-C-E

4+9+12+12+9+7+5+14+3+5=80–> 80%

And

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

8+1+18+4+23+15+18+11=98–>98%

Also

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

1+16+20+9+20+21+4+5=96–>96%

and

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

1+20+20+9+20+21+4+5=100–>100%

and

B-U-L-L-S-H-I-T

2+21+12+12+19+8+9+20=103–>103%

Wow, if your goal is to be perfect of 100%, then Being Rage Free is NOT ENOUGH if you don’t study or work at all, Being Diligent is GOOD, while Hard Work is GREAT. Hard Work and Aptitude can help you get close,  but you never fully reach it.

Attitude is 100%, which is the ideal tool you need in life to arrive at your destinations.

Bullshit may blow you away and

what do you think of the word

S-O-L-I-T-U-D-E,

19+15+12+9+20+21+4+5=___?–> ____%.

please add these numbers yourself, find the answer, then tell everyone about your insight or conclusion by saying:

Solitude is________________.

Thank you in advance.

For more advanced readers or math fans, you can try

A-S-S-K-I-S-S-I-N-G

1+19+19+11+9=19+19+9+14+7=_____–>____%.

Discover FUN in these computations and wordings.

Math is cool, How about you?
