If we have 45 blocks and we add a further 19 blocks, how many blocks will we have in total?
To solve this problem, we need to find the total number of blocks after adding 19 blocks to an existing 45 blocks.
Step 1: Identify the numbers involved:
Step 2: Perform the addition calculation:
Now, let's explain the addition in detail:
Thus, the total number of blocks is .
The correct answer choice is: 4
Therefore, the solution to the problem is .
If we have 67 blocks in total, how many blocks will remain if we remove 5 tens and 4 ones?
Place value alignment ensures you're adding the right digits together! If you don't line up properly, you might add tens with ones and get the wrong answer.
When digits add up to 10 or more, you have extra tens! Write the ones digit in your answer and 'carry' the tens digit to the next column to the left.
Try counting backward: Start with 64 and subtract 19. You should get 45! Or use the visual: count all the blocks in the diagram.
Practice with smaller numbers first! Try 23 + 18: ones place 3 + 8 = 11 (write 1, carry 1), tens place 2 + 1 + 1 = 4. Answer: 41.
