I'm not sure, this is what my textbook says:

Identity Laws

There is a unique number 0 with the property that 0+a = a+0 = a

There is a unique number 1 with the property that 1*a = a*1 =a

I have no idea what that means....

By the way i'm not very good at maths so a simple explanation would be appreciated...

What are these laws and how do they fit into mathematics? I am having trouble understanding them...

What are all the possible isomers of Propane?

What are Amino Acids?

why are alpha and beta particles deflected in opposite directions in a magnetic field?

and also

are x-rays most similar to alpha, beta or gamma rays?

Why wolud you expect alpha particles, with their greater charge, to be less able to penetrate materials than beta particles of the same energy?

I am just starting a biology course so if it is possible could someone please tell me about these things?

thanks

Distance, speed, constant acceleration, motion time graphs (including gradients and simple areas), mass, force (push, pull, friction, weight, reaction)

i have had trouble understanding what these things are and how to calculate them so if someone could help me that would be great!

What are geometric isomers?

iv'e been having trouble understanding what they are and what they are for.

thanks in advance!
