To calculate $1836 + 2164$, follow these steps:

1. Align the numbers by place value:

   & 1 & 8 & 3 & 6 \\ + & 2 & 1 & 6 & 4 \\ \end{array}$$

2. Add the digits from right to left:

   • Units place: $6 + 4 = 10$. Write down 0 and carry over 1.
   • Tens place: $3 + 6 = 9$, and add the carried over 1, so $9 + 1 = 10$. Write down 0 and carry over 1.
   • Hundreds place: $8 + 1 = 9$, and add the carried over 1, so $9 + 1 = 10$. Write down 0 and carry over 1.
   • Thousands place: $1 + 2 = 3$, and add the carried over 1, so $3 + 1 = 4$.

3. Write down the result:
   $1836 + 2164 = 4000$
