Subtract 2 Tens and 3 Ones: Finding Remaining Blocks from 79

Let's solve the problem step by step:

We begin with a total of $79$ blocks.

First, we need to determine how many blocks are removed:

• Two tens, which equals $2 \times 10 = 20$ blocks.
• Three ones, equaling $3$ blocks.

Add the blocks removed together: $20 + 3 = 23$ blocks removed in total.

Now, subtract the total blocks removed from the starting total:

$\text{Total remaining} = 79 - 23 = 56$

Therefore, the number of blocks remaining is $56$.
