Sum of Product is the abbreviated form of SOP. Sum of product form is a form of expression in Boolean algebra in which different product terms of inputs are being summed together. This product is not arithmetical multiply but it is Boolean logical AND and the Sum is Boolean logical OR.

Canonical SoP form means Canonical Sum of Products form. In this form, each product term contains all literals. So, these product terms are nothing but the min terms. Hence, canonical SoP form is also called as sum of min terms form. This Boolean function will be in the form of sum of min terms.

The main difference between SOP and POS is that the SOP is a way of representing a Boolean expression using min terms or product terms while the POS is a way of representing a Boolean expression using max terms or sum terms. Furthermore, SOP and POS are two methods of representing Boolean expressions.

Comparison operators — operators that compare values and return true or false . The operators include: > , < , >= , <= , === , and !== . Logical operators — operators that combine multiple boolean expressions or values and provide a single boolean output.

The result of this comparison operator is a Boolean value of True, or False….

These logical operators are used to compare two values of the same type….

• true. to the first expression and . false. to the second;
• false. to the first expression and . true. to the second; and,
• false. to both statements.
