Grade-7 Math Probability Project
During UAS-BN for grade-6, for daily math activities grade-7 is to make math probability project such as probability games and the rules of playing. The product should be colorful and attractive. The rules of playing can be fair or not-fair games.
Materials: You may use dices, playing cards, dominoes, spinners, etc.
If you have difficulty to find the idea, you may find it from internet or from the books. The project will be played together with grade-6 after UAS-BN end and grade-6 joints with grade-7 in math class.
Find the idea of this project! You may do this project together in math's class group.
Setup Al-Qur'an into MS-Word
When we are typing by using MS-Word (MS-Office), it is difficult to type Al-Qur'an and its tafseer.
Now Easy!
I want to share the software program that should be setup into MS-Word, just click this setup-quran-in-word-ind. After downloaded, extract the rar file then run exe file until installation process done. Then open MS-Word and you will see new icon "Al-Quran" menu on the top of MS-Word.
To be expert using this "Al-Quran" menu, try to explore it. . .
Semoga ALLOOH SWT memberikan Rahmat-Nya !
Math Magic Games
Situation :
Call your friends and tell them that you are able to read their mind. Ask them to think a number and don't let you know the number they are thinking. When they are counting you may act as a magician by closing your eyes and raising your hands to the sky.
Instruction :
"Think a number and don't let me know the number. Multiply the number with three, added by four, multiplied by two, divided by 2, added by two, divided by three and the last is subtracted by the number in your mind"
They will be surprise after you tell them that the the number their thought is "two".
Secret :
Whatever numbers they put in, the answer is always "two". Why? By using algebra equation!
If the number given is x, so we get the formula :
{[(2(3x+4)):2]+2}:3-x=2
The way :
If you want the answer is "three" just follow these steps:
(x+3)-x = 3
and put times 2 (or whatever number you want to put in) :
(2(x+3):2)-x=3
Expand the equation (2x+6):2-x=3
Change the equation to be [(2x+4)+2]:2-x=3
and put times 3 (or whatever number you want to put in) :
{[3(2x+4):3]+2}:2 - x = 3
And the last, expand the equation :
{[(6x+12):3]+2}:2 - x = 3
So, the instruction will be "Multiply the number you're thinking with 6, add 12, divided by 3, added by 2, divided by 2, and subtracted by the number"
And prove it if we put the number is 10 :
6 x 10 = 60
60 + 12 = 72
72 : 3 = 24
24 + 2 = 26
26 : 2 = 13
13 - 10 = 3
Have fun with math !!!

Basic Algebraic Properties
Algebraic Properties of Real Numbers
The basic algebraic properties of real numbers a,b and c are:
1. Closure: a + b and ab are real numbers2. Commutative: a + b = b + a, ab = ba
3. Associative: (a+b) + c = a + (b+c), (ab)c = a(bc)
4. Distributive: (a+b) c = ac+ bc
5. Identity: a+0 = 0+a = a
6. Inverse: a + (-a) = 0, a(1/a) = 1
7. Cancellation: If a+x=a+y, then x=y
8. Zero-factor: a0 = 0a = 0
9. Negation: -(-a) = a, (-a)b= a(-b) = -(ab), (-a)(-b) = ab
Algebraic Combination
Factors with a common denominator can be expanded:
Fractions can be added by finding a common denominator:
Products of fractions can be carried out directly:
Quotients of fractions can be evaluated by inverting and multiplying:

Math Project # 8 - Algebra
Due date : Monday, February 2, 2009
1. Find the number described in each problem by writing and solving an equation
a) If Sarah substracts five times her number from 24, she gets 4. What is Sarah's number?
b) Twice Bill's number added to 17 is 7. What is Bill's number?
c) The sum of 4 times a number and 14 is 16. What is the number?
d) If Susan substracts 11 from one fourth of her number she gets 11. What is Susan's number?
2. The school drama club is performing its summer play at the community theatre. Props for the play cost $250, and the theatre is charging the drama club $1.25 for each ticket sold. So, the total cost, C, for the drama club to put on the play is C=1.25N+250, where N is the number of tickets sold. Customers pay $4 for each ticket, so the total amount collected from ticket sales is T=4N.
a) What is the cost if 213 tickets are sold?
b) How much are the total ticket sales if 213 tickets are sold?
c) What is the drama club's profit or loss if 213 tickets are sold?
d) If the total ticket sales are $780, how many people attended the play?
e) What is the cost of putting on the play for the number of people you found in d)?
f) How many tickets does the drama club need to sell to break even?
g) The drama club would like to earn a profit of $500 from play. How many tickets need to be sold for the club to meet this goal?
