E/R E/R E/I ER R/E RE

Which of the following are statements of true axioms?

When A = C and B = C, then A = B because both are equal to C, which supports the axiom: Quantities equal to the same quantity are equal to each other. You can move any quantity from one side of the equal sign to the other side if you keep the sign the same. When equal numbers are added to both sides of the equation, the sums are not equal. When equals are multiplied by equals, the products are unequal. When unequal numbers are subtracted from both sides of the equation, the remainders are equal. When A = C and B = C, then A = B because both are equal to C, which supports the axiom: Quantities equal to the same quantity are equal to each other.
