i need a definition of palindromic numbers, fibonacci sequence, pascal's triangle, square numbers, triangular numbers and the sieve of Eratosthenes.i know what they are but i really don't understand our maths teacher because she never answers any questions. and what are they named after? how can we use them in the real-world, everyday life people always say that we use it in everyday living.

A palindrome is something that reads the same backwards and forwards. A well-known palindromic sentence is something Napoleon might have said: "Able was I ere i saw Elba."
The word "ere" is a palindrome itself. So is the number 121, for example.
If you look up the sieve of Eratosthenes in wikipedia.org, you get a lively demonstration of it; it's a way to find prime numbers.
You'll probably find all your answers either by asking google or wikipedia.
