Remove Ones Digit: Calculate Remaining Value from 559 Blocks

Question

If we have 559 blocks and we only remove the ones, how many blocks will remain?

To find how many blocks remain after removing the ones digit from 559, we follow these steps:

Step 1: Determine the ones digit in 559. The number is 559, so the ones digit is 9.
Step 2: Subtract the ones digit from the total number of blocks. This means calculating $559 - 9$ .
Step 3: Perform the subtraction: $559 - 9 = 550$ .

Therefore, when the ones digit is removed, 550 blocks remain.

The correct answer to the problem is $559 - 9 = 550$ .

$559-9=500$
