To solve the given problems using the column method, we will perform the calculations step by step.

### Problem 1: $$ \mathrm{R} 20,89+\mathrm{R} 31,99 $$

Given:
$$ \mathrm{R} 20,89+\mathrm{R} 31,99 $$

Using the column method:
$$ \begin{array}{r} \text { ro, 89 } \ +31,99 \ \hline 1232,88 \end{array} $$

The result of $$ \mathrm{R} 20,89+\mathrm{R} 31,99 $$ is $$ \mathrm{R} 1232,88 $$.

### Problem 2: $$ 4 \times 0,287 $$

Given:
$$ 4 \times 0,287 $$

Using the column method:
$$ \begin{array}{r} \frac{1,3}{6,87} \ x \quad 1 \ \hline 1,148 \end{array} $$

The result of $$ 4 \times 0,287 $$ is $$ 1,148 $$.

### Problem 3: $$ 5,897 \div 2 $$

Given:
$$ 5,897 \div 2 $$

Using the column method:
$$ \begin{array}{r} \text { ro, 89 } \ +31,99 \ \hline 1232,88 \end{array} $$

The result of $$ 5,897 \div 2 $$ is $$ 2,948,5 $$.
- $$ \mathrm{R} 20,89 + \mathrm{R} 31,99 = \mathrm{R} 1232,88 $$ - $$ 4 \times 0,287 = 1,148 $$ - $$ 5,897 \div 2 = 2,948.5 $$
