Math is very practical, man!
For example, you are going to date a hotie, and it’s 2x^2+6 more days to go (x=2). You will need to budget your money for 72x^3+45x+6 strands of spaghetti (x=3), 25x^2-15x+325 milliliters of red wine (x=5). You will also get the time needed for your date.
Another example, you need to buy a 20y-5 litter of cooking oil, where y=3, which cost $12x^2-3x+4, where x=3. You pay $15x^2+10x-15, where x=3. You will now need to compute for the change.
Or another is that you are traveling 40x-2 km per hour, x=2, and you reached your destination in 3y-5 hours, y=3. You will now need to compute for the distance you traveled.
Those are just PRACTICAL examples of Math.

when you need to add things subtract-mostly in monetary matters. A simple example would be in the grocery. More complex would be if you are running a business and you have to figure out how much a large shipment will cost you based on percents and how many you buy...

I use math to convert binary numbers to hexadecimal and decimal, as well as to calculate subnet masks. I have used it to figure out how many of each kinds of plants, based on average yield and consumption, to put in my garden. I have also used it to calculate how many gallons of primer and paint to buy for my house. Anyone in construction uses math to calculate area, volume, angles and such. -yk

1 tank of ecstasy = 1,000 pills
1,000 * $5.75 = $5,750
100 pills in a jar
1,000 / 100 = 10 jars of ecstasy
$1,000 per jar X 10 jars = $10,000
$10,000
- $5,750
= $4,250 profit

o.k. like if you are trying to time yourself from the time you leave home until you get to work. If you start at 8am and it takes 20 min to get there you would leave your house at around 7:20 just in case you get caught in heavy traffic.

sometimes it feels that way during school or whatever, thinking "well, are we ever gonna use this stuff anyways?" you use it for buying things and for measuring things and so on. the list is longer than you may think.
