Make It Real Learning activity developer and award-winning author, Frank Wilson, will be part of an all-star lineup of authors and educators at the Cengage Learning TeamUP Faculty Programs Mathematics Conference in Scottsdale, Arizona on Feb 10, 2012. Wilson’s workshop, entitledCaptivating Contexts for College Algebra, will feature intriguing real-world contexts that interest and engage students in learning. By creating mathematical models for real-world situations, students learn more than math: they learn about the world in which they live. Participants will receive an activities packet featuring fascinating contexts ranging from the Nintendo Wii to the Apple iPod. A copy of the presentation and packet may be freely downloaded.
hi i’m Mostafa from Egypt and i ‘m a software developer (Computer programer)
i would like to thank you for your effort, and i would like to participate a small problem solved using math :
Every computer programmer have to learn math specially exponents,
and here is the reason
computer memory is strictly limited by the amount of hardware you have.
so you need to know the total amount of numbers you can store in one block of memory (in computer numbers can represent any thing audio-images-text..)
and also in cracking passwords in a way called brute force where all the possible letters and numbers are tried,
and to do that you can use the simple function :
x = y^n
Where x is the total amount of numbers(values) that can be represented(stored) in a block of memory that its size(store places) is n,
y is the count of digits in the counting system you use for example
binary = 2 (0 or 1)
decimal = 10 (0 or 1 or 2 or 3 or 4 or 5 or 6 or 7 or 8 or 9)
hexadecimal = 16 (0 or 1 or 2 or 3 or 4 or 5 or 6 or 7 or 8 or 9 or a or b or c or d or e or f)
for example to know the maximum value you can represnt by a 2 digits(boxes) decimal number:
value = 10^2 = 100 (from 0 to 99)
