The vector subtraction………………………………bya vector.

Explanation

To solve the problem of vector subtraction, let's break it down step by step.

### Step 1: Understand Vector Subtraction
Vector subtraction involves taking one vector away from another. In mathematical terms, if we want to subtract vector **b** from vector **a**, we express this as:
\[ \vec{R} = \vec{a} - \vec{b} \]

### Step 2: Rewrite Vector Subtraction as Addition
To perform vector subtraction, we can rewrite it in terms of vector addition. Specifically, we can express the subtraction of vector **b** from vector **a** as:
