Mathematical Smilies

For those who don’t get it or are stuck on what these mean:

Following down the Left side column we have inverse, square, cube, sine (sign), and log.

The Right side’s a little more complicated.

The first one is “real” – when applied to a complex number – that is, one with real and imaginary (designated by some factor times “i”) parts – you take the real component only and drop the imaginary component. i.e. You drop the i’s (eyes). “Imag” (imaginary) is the converse of “real”, so that would be only the i’s.

The inverted triangle is a math operator called “grad”, and it takes the gradient of a function. When applied to a vector – and we know it’s a vector because of the cross product operator – it’s known as the “curl”.

Then finally, we have “root”.

Yeah, I know – if you have to explain it, it’s not funny.

The Math Test

California officials have determined that students would probably do better with math word problems, if they could relate them to real life examples. Towards that end, may I present:

The City of Los Angeles
High School Math Proficiency Exam

Name:_______________________________
Gang:___________________________

1. Johnny has an AK-47 with an 80-round clip. If he misses 6 out of 10 shots and shoots 13 times at each drive-by shooting, how many drive-by shootings can he attempt before he has to reload?

2. Jose has 2 ounces of cocaine and he sells an 8-ball to Jackson for $320 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. Jarome want to cut his 1/2 pound of heroin 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 BMWs, 3 4X4s, how many Chevies will he have to steal to make $800?

6. Raoul is in prison for 6 years for murder. He got $10,000 for the hit. If his common law wife is spending $425 per month, how much money will be left when he gets out of prison, and how many years is he likely to get for killing the bitch that spent his money?

7. If the average spray can covers 22 square feet and the average letter is 3 square feet, how many letters can be sprayed with 3 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. 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?

10. Salvador was arrested for dealing crack & 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 jumping bail?
