(The R's are real numbers)
a) Prove that if f:R-R preserves subtraction, then f(0)=0
b) Give any example of a function that preserves subtraction
c)Prove that if f:R-R preserves subtraction, and if 0 is the only number that f maps to 0, then f must be injective

I was in my garage the other day, at night, in my car, closed doors and windows and it was off. Everything was so silent that I heard silence! It sounds like a tuning fork, and diminishes slowly. Is it in my head or am I really hearing that? What causes it?

how would you solve: 4x - 2y = 8 so that it can be in y= form

would the answer be 2y - 4x + 8, then you can divide by 2 and get
y - 4/2x + 8/2......is this right

how would you solve: x = 3y +2 so that it is in y= form?

would the answer be -3y - x +2 then you can divide by -3 but what will you get?

I am getting quick and dirty lessons on mathematics involving operation based on Fermat and Euler's Theorems, along with Chinese Remainder Theorems, with their usage in modern cryptography. My comprehension would be better if I could school myself in the basics leading up to these. What type of mathematics categories would these theorems be classified into, and does anyone recommend any texts?
