Okay, Emmanuel, let's finish up the rest of this page! Step 1: Solve the subtraction problem with the circles. There are 20 circles in total. 12 of them are crossed out. To find how many are left, we subtract the crossed-out circles from the total. 20 - 12 = 8 Step 2: Complete the addition problem with the empty boxes. The problem shows a sum of 17 + 23. First, add the ones digits: 7 + 3 = 10. Write down 0 and carry over 1 to the tens place. Next, add the tens digits: 1 + 2 + 1 (carry-over) = 4. The sum is 40. c 17 \\ + 23 \\ 40 \\ That's 2 down. 3 left today — send the next one.
