Boolean Algebra

What is Boolean algebra?

Boolean algebra is one topic where most students get confused. But it is pretty simple if you understand the logic behind it. Boolean algebra is the branch of algebra wherein the values of the variables are either true or false, generally denoted by 1 and 0 respectively. Where in elementary algebra we have the values of the variables as numbers and primary operations are Addition and multiplication.

Let’s learn Boolean algebra laws in a simpler way.

Boolean algebra problems can be solved using these Boolean algebra laws.

There are few boolean algebra rules to be followed to while solving problems
