Place Value Subtraction: Remove 41 from 85 Using Base-10 Blocks

To solve this problem, we begin by calculating the total number of blocks to remove.

Step 1: Calculate the blocks in 4 tens.

• A "ten" refers to 10 blocks. Thus, 4 tens equal $4 \times 10 = 40$ blocks.

Step 2: Calculate the total blocks to remove by combining tens and ones.

• We are also removing 1 more block, so the total becomes $40 + 1 = 41$ blocks.

Step 3: Subtract the total removed blocks from the initial total to determine how many blocks remain.

• $85 - 41 = 44$.

Therefore, the number of blocks remaining is $44$.
