Subtract 7 from 27 Blocks: Calculate the Remaining Quantity

To solve this problem, we'll follow these steps:

• Step 1: Identify the total number of blocks, which is $27$.
• Step 2: Identify how many blocks to remove, which is $7$.
• Step 3: Subtract the number of blocks to be removed from the total number of blocks.

Now, let's perform the calculation:
Step 3: We calculate $27 - 7 = 20$.

Therefore, the number of blocks remaining after removing 7 blocks from 27 is $20$.
