Step-by-step solution

Let's solve the problem step by step:

We begin with a total of 79 79 blocks.

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

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

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

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

Therefore, the number of blocks remaining is 56 56 .
