Understanding vector multiplications can be daunting, especially if you’re new to the concept. But fear not! With a **Dot Product Calculator**, you can easily handle these calculations without breaking a sweat. This handy tool is perfect for students, professionals, and anyone who needs to perform vector multiplications quickly and accurately.

**What is a Dot Product?**

The dot product, also known as the scalar product, is a fundamental operation in vector algebra. It takes two equal-length sequences of numbers (usually coordinate vectors) and returns a single number. This operation is widely used in various fields, including physics, engineering, and computer graphics.

**How to Calculate the Dot Product**

Calculating the dot product involves multiplying corresponding entries of the two vectors and then summing up all the products. For example, if you have two vectors A and B:

A=[a1,a2,a3]A = [a_1, a_2, a_3]A=[a1,a2,a3]

B=[b1,b2,b3]B = [b_1, b_2, b_3]B=[b1,b2,b3]

The dot product A · B is calculated as:

A⋅B=a1b1+a2b2+a3b3A \cdot B = a_1b_1 + a_2b_2 + a_3b_3A⋅B=a1b1+a2b2+a3b3
