Step-by-step explanation:
To find out how many toys the students of St. John's school collected in total from September to November, we need to sum up the toys collected in each month:
\[ 9812 + 18456 + 14003 \]
Let's perform the addition step by step:
1. Add September and October:
\[ 9812 + 18456 = 28268 \]
2. Add November to the result from step 1:
\[ 28268 + 14003 = 42271 \]
Therefore, the total number of toys collected by the students from September to November is \( \boxed{42271}/)
