Question

So acorrding to algebra an equal sing (=) symbolizes that an equation which has RHS(right hand side) and LHS (left hand side)are equal but what if the RHS and LHS are actualy not equal,then why is the equal sing used. This is actually a doubt not a question

Answer 1

Answer:

In mathematics, LHS is informal shorthand for the left-hand side of an equation. Similarly, RHS is the right-hand side. The two sides have the same value, expressed differently, since equality is symmetric.

We will be proving LHS = RHS using 2 methods. In the first method we will start from LHS and solve LHS part using boolean algebraic laws to get the RHS value. In the second method we will make the use of Truth table to prove LHS = RHS.

Answer 2

Answer:

If they are not equal, then we don't use equal sign
