This is kinda neat...
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

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

1. Johnny has an AK-47 with
an 80 round clip. If he missed
6 out of 10 shots and shoots 18 times at each drive-by
shooting, how many drive-by shootings can he attempt
before he shoots 50 people?
2. Jose has 2 ounces of cocaine
and he sells an 8 bal to
Jackson for $820 and 2 grams to Billy for $85 per gram.
What is the street value of the balance of the cocaine
if he doesn't cut it?
3. Rufus is pimping for three
girls. If the price is $65
for each trick, how many tricks will each girl have to
turn so Rufus can pay for his $800 per day crack habit?
4. Jerome wants to cut his 1/2
pound of heroine to make 20%
more profit. How many ounces of cut will he need?
5. Willie gets $200 for stealing
a BMW, $50 for a Chevy, and
$100 for a 4x4, if he has stolen 2 BMW's and 3 4x4's, how
many Chevy's will he have to steal to make $800?
6. Raul is in prison for 6 years
for murder. He got $25,000
for the hit. If his common law wife is spending $250 per
month, how much will be left when he gets out of prison
and how many years will he get for killing the bitch that
spent his money?
7. If the average spray can
covers 22 sq. ft. and the average
letter is 8 sq. ft., how many letters can a tagger spray
with 8 cans of paint?
8. Hector knocked up 6 girls
in his gang. There are 27 girls
in the gang. What percentage of the girls in the gang has
Hector knocked up?
9. Rosie's sole source of income
is shoplifting. If she gets
10 cents on the dollar from her fence, how much merchandise
must she shoplift each week to make $250.
10. Mike carjacked a Chevy Camaro
for his date Saturday night
with his young 14 year old girlfriend. He was arrested
that night while making his girlfriend in the backseat.
How much prison time is he looking for the carjacking and
for statutory rape, even though the girl looked legal?
Assume no prior convictions in arriving at your answer.
11. Thelma can cook dinner for her 16 children for $7.50
per night. She gets $234 a month welfare for each child.
If her $325 per month rent goes up 15%, how many more
children should she have to keep up with her expenses?
12. Salvador was arrested for
dealing crack and his bail
was set at $25,000. If he pays a bail bondsman 12% and
returns to Mexico, how much money will he lose by
City Of Los Angeles High School Math Proficiency Exam (Answers)
1. Johnny hits 15*(4/10) people
per drive-by, which means
that he will have to participate in 9 drive bys to shoot
50 people. However, he will have completed two drive-by
shootings and be just starting the third when he has to
reload. Since he only stole a single clip, he'll only
have shot 16 people when the homeboys with the Uzis' make
Swiss cheese out of him.
2. At 454 grams per pound, 2oz
of the rock = 56.75 grams.
An "8 ball" is 8 grams, so pony has sold 10 grams total
and has 46.75 grams left. If he keeps selling 8-balls,
he can sell 5 more (for a total of 5*$320=$1,600) and
have 6.75 grams for his own nose. If he sells 2 gram
packs, he can sell (46/2-23) packs at $85 apiece =
(23*$85)=$1,955. However, he could divide it into small
parts, bake it up into crack and sell the rocks for an
even larger profit. This problem is really more suited
for the Gang Multi-Variable Economics Test.
3. 800/$64=12 tricks plus a
dance. Also, Ron should consider
making a deal with Pony from Question #2.
4. If he sells the cut heroin
at the same price per unit
volume, he will need 20% more volume. 20% of 1/2 pound
(=8oz) is 1.6oz. So, Jarome will need 1.6oz of cut to add
to the 8 oz of heroin to get 20% more volume. He will
want a cut which looks similar to raw heroin and has
approximately the same melting point. Plain sugar or
laundry detergent are suggested. Laundry detergent has
the added benefit of removing the possibility of customer
complaints, but will sharply limit repeat business.
5. Willie has made 2*$200 +
3*$100=$700 dollars from his
theft so far. He needs $100 more, so he needs to steal
$100/$50=2 more Chevy's. However, he will probably want
to steal 4 Chevy's so he can take the extra two and make
a really def low-rider.
6. 6 years*12 months/year*$250/month=$18,000.
have $25,000 - $18,000 = $7,000 left when he gets out of
prison. If Raul kills her in the USA, he should expect
to get 6 years. However, if he takes her down to Mexico
and buries her scrawny, track-marked butt in the desert,
he can get off scott free.
7. 3 cans of paint will cover
3*22=66 square feet. 66/4=16
letters with a little paint left over to spray in the
eyes of the cop who's comin' after you. Or the tagger
could do 15 letters and a bitchin' skull.
8. 6/27=22% of the girls.
However, 2 of them are lying
because they've been sleeping with Pedro, Hector's
lieutenant. So, in actuality, Hector only knocked up
4/27 or 14.8%.
9. Solve X/10=250 for X, X=$2,500.
10. Mike is only 12 so he will
serve no time and will be
doing it again to his girlfriend in the lot in someone
else's car next Saturday.

Teaching Math in 1960:
A logger sells a truckload of lumber for $100. His
cost of production is 4/5 of the price, or $80. What
is his profit?
Teaching Math in 1970: - (new
A logger exchanges a set "L" of lumber for a set "M" of
money. The cardinality of set "M" is 100. Each element
is worth one dollar. Make 100 dots representing the
elements of the set "M". The set "C", the cost of
production contains 20 fewer points than set "M".
Represent the set "C" as a subset of set "M" and answer
the following question: What is the cardinality of the
set "P" of profits?
Teaching Math in 1980:
A logger sells a truckload of lumber for $100. His cost
of production is $80 and his profit is $20. Your
assignment: Underline the number 20.

By cutting down beautiful forest trees, the logger makes
$20. What do you think of this way of making a living?
Topic for class participation after answering the question:
How did the forest birds and squirrels feel as the logger
cut down the trees? There are no wrong answers.
Teaching Math in 1996:
By laying off 40% of its loggers, a company improves
its stock price from $80 to $100. How much capital
gain per share does the CEO make by exercising his
stock options at $80. Assume capital gains are no longer
taxed, because this encourages investment.
Teaching Math in 1997:
A company outsources all of its loggers. They save on
benefits and when demand for their product is down the
logging work force can easily be cut back. The average
logger employed by the company earned $50,000, had 3
weeks vacation, received a nice retirement plan and
medical insurance. The contracted logger charges $50 an
hour. Was outsourcing a good move?
Teaching Math in 1998:
A logging company exports its wood-finishing jobs to its
Indonesian subsidiary and lays off the corresponding half
of its US workers (the higher-paid half). It clear-cuts
95% of the forest, leaving the rest for the spotted owl,
and lays off all its remaining US workers. It tells the
workers that the spotted owl is responsible for the absence
of fellable trees and lobbies Congress for exemption from
the Endangered Species Act. Congress instead exempts the
company from all federal regulation. What is the return
on investment of the lobbying costs?

Subj: Proof That All Numbers Equal Zero And That 1$ = 1c
Theorem : All numbers are equal
Proof: Suppose that a=b. Then
a = b
a^2 = ab
a^2 - b^2 = ab - b^2
(a + b)(a - b) = b(a - b)
a + b = b
a = 0
Theorem: 1$ = 1c.

Subj: Equation About Money, Work, and Knowledge (S45)
From: RobertTompkins on 97-12-06
Engineers and scientists will
never make as much money as
business executives. Now a rigorous Mathaematical Proof
that explains why this is true:
Postulate 1: Knowledge is Power. Postulate 2: Time is Money.
As every engineer knows,
----------- = Power
Since Knowledge = Power, and Time = Money, we have
---------- = Knowledge
Solving for Money, we get:
------------------ = Money
Thus, as Knowledge approaches
zero, Money approaches infinity
regardless of the Work done.
Conclusion: The Less you Know, the more you Make.
Note: It has been speculated

For Work, Knowledge And Money (2ed Vers.)
From: Amy's Humor Archive on 06/27/97
After applying some simple algebra
to some trite phrases
and cliches, a new understanding can be reached of the
secret to wealth and success.
Here it goes.
Knowledge is Power
Time is Money and as everyone knows, Power is Work divided
So, substituting algebraic equations
for these time worn
bits of wisdom, we get:
K = P (1)
T = M (2)
P = W/T (3)
Now, do a few simple substitutions:
Put W/T in
for P in equation (1), which yields:
K = W/T (4)
Put M in for T into equation (4), which yields:
K = W/M (5).
Now we've got something. Expanding back into English, we get:
Knowledge equals Work divided by Money.
What this MEANS is that:
1. The More
You Know, the More Work You Do,
2. The More You Know, the Less Money You Make.
3. The Less you Know, the More you Make.
Solving for Money, we get:
M = W/K (6)
Money equals Work divided by Knowledge.
From equation (6) we see that
Money approaches infinity as
Knowledge approaches 0, regardless of the Work done.
What THIS MEANS is:
The More you Make, the Less you Know.
Solving for Work, we get
W = M x K
Work equals Money times Knowledge
From equation (7) we see that
Work approaches 0 as
Knowledge approaches 0.
What THIS MEANS is:
The stupid rich do little or no work.
Working out the socioeconomic
implications of this
breakthrough is left as an exercise for the reader.

Subj: Proof That Girls Are Evil (S224)
From: One of Chris Guinon's students 5/15/01
We all know that girls take time and money
Girls = time x money
and we know that time is money
time = money
Therefore girls = money x money or (money)2
Now we all know money is the root of all evil
money = square root(evil)
so girls = ( square root(evil) )2
Therefore girls = evil
Subj: Other Proofs
Here's my personal favorite:
Use integration by parts to find the anti-derivative of 1/x.
One can get the amusing result that 0=1. (Until you realize
you have to put in the limits.)
Theorem: 4 = 5
16 - 36 = 25 - 45
4^2 - 9*4 = 5^2 - 9*5
4^2 - 9*4 + 81/4 = 5^2 - 9*5 + 81/4
(4 - 9/2)^2 = (5 - 9/2)^2
4 - 9/2 = 5 - 9/2
4 = 5
Theorem: All numbers are equal.
Choose arbitrary a and b, and let t = a + b. Then
a + b = t
(a + b)(a - b) = t(a - b)
a^2 - b^2 = ta - tb
a^2 - ta = b^2 - tb
a^2 - ta + (t^2)/4 = b^2 - tb + (t^2)/4
(a - t/2)^2 = (b - t/2)^2
a - t/2 = b - t/2
a = b
So all numbers are the same, and math is pointless.
