BOOLEAN ALGEBRA
In mathematics and mathematical logic, Boolean algebra is the branch of algebra in which the values of the variables are the truth values true and false, usually denoted 1 and 0 respectively.
Boolean algebra was really easy for me to understand, as it just had some rules I had to follow and it just like we do in math, instead of a mixture of numbers and variables, it just had variables. The rules were really easy to understand and most of them were common sense, like multiplying a variable with 1 would be the variable. We also had to convert Boolean expressions into truth table which was a little hard, we had to convert Boolean expressions into k-maps and logic gates.
