<h3>What is distributive property of multiplication over addition?</h3>
Suppose a, b and c are three numbers. Then we have:

(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)
The product result of the given expression is obtained as:

Thus,
