Logic and Proof
Identify the property exemplified here. Turkey Sandwich = Turkey Sandwich.
We're given that A = B and C = D. As a result, we state that A – C = B – D. This equation is an example of which property or properties?
If A = X, B = Y, and C = Z, then can we say that A(B + C) = Z × Y + X × Z?
If A + B = C, then is it possible to claim that X(A + B) = C × X? Which properties allow us or forbid us from doing so?
