What number do we get if we add 3 tens and 4 units to the number 55?
To solve this problem, we'll follow these steps:
Let's work through each step:
Step 1: We need to add three tens to 55. Three tens equal .
Thus, adding 30 to 55 gives us:
Step 2: Now, we add the 4 units to the result of Step 1 (which is 85).
Adding 4 gives us:
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?
3 tens means 30! Each ten is worth 10, so 3 tens = . It's like having 3 groups of 10 objects each.
Because place value matters! The '3' represents 3 tens (30), not 3 units. You need to add 30 + 4 + 55 = 89, not 3 + 4 + 55 = 62.
Yes! Think of it as one addition: 55 + 34 = 89. Since 3 tens and 4 units = 34, you can add them together first, then add to 55.
Break down 89 into place values: 8 tens and 9 units. Starting with 55 (5 tens, 5 units), we added 3 tens and 4 units. Check: 5 + 3 = 8 tens, 5 + 4 = 9 units ✓
Great question! If units exceed 9, you regroup (carry over). For example: 7 units + 6 units = 13 units = 1 ten and 3 units. Add that extra ten to the tens column!
