Hlanganisa uphinde ususe uze ufinyelele koku

The main instruction "Hlanganisa uphinde ususe uze ufinyelele koku..." means "Add and subtract until you reach...". The instruction "Qedela lokhu okulandelayo:" means "Complete the following:".
For the first row, we have 1 acorn in the first box and 4 acorns in the second box.
We need to add these quantities:

$$1 + 4 = 5$$

The completed phrase is: 1 nama- 4 kunginika ezi- $\boxed{\text{5}}$

For the second row, we have 2 fish in the first box and 3 fish in the second box.
We need to add these quantities:

$$2 + 3 = 5$$

The completed phrase is: 2 nezi- 3 kunginika ezi- $\boxed{\text{5}}$

For the third row, we have 3 roses in the first box and 2 roses in the second box.
We need to add these quantities:

$$3 + 2 = 5$$

The completed phrase is: 3 nezi- 2 kunginika ezi- $\boxed{\text{5}}$

For the fourth row, we have 2 umbrellas in the first box. The second box and the total box are empty. Based on the pattern of the previous problems, it is likely that the target total is 5.
To reach a total of 5 from 2 umbrellas, we need to add 3 more umbrellas.

$$2 + 3 = 5$$

The completed phrase is: 2 nezi- $\boxed{\text{3}}$ kunginika ezi- $\boxed{\text{5}}$
