If 2 segments have the same length they are known as 'congruent segments' IE: segment AB=segment AC (or AB=AC) then AB @ AC (or AB is congruent to AC)
A*B=B*A is an example of the commutative property of multiplication.
If, as is normal, ab represents a times b, etc then ab + ab + cc = 2ab + c2 which is generally not the same as abc.
Yes.
Yes, provided it is the ray. If AB is a vector then the answer is no.
the basic number properties in math are associative, commutative, and distributive associative: (for addition) a+(b+c)=(a+b)+c (for multiplication) a(bc)=(ab)c or a*(b*c)=(a*b)*c commutative: (for addition) a+b=b+a (for multiplication) a*b=b*a or ab=ba distributive: a(b+c)=ab+ac or a(b+c)=a*b + a*c

Calculus AB tends to be easier due to it being mostly composed of the basic introductory to Calculus. Whereas Calculus BC contains information from AB but as well as further information which could possibly be somewhat more rigorous than AB.
AB is simplified to the furthest extent because you do not know what A or B is, and multiplication is one of the four simplest methods of math (along with addition, subtraction, and division).
a(b + c) = ab + ac where a, b and c are any real numbers.
