Solve the addition problem:
In this problem, we need to add 66 and 24. Let's break this down step-by-step using the standard addition method:
The units digits are 6 and 4. Adding these gives us .
Write down 0 in the units place, and carry over 1 to the tens place.
The tens digits are 6 and 2, along with the carried 1. Adding these numbers gives us .
Placing the digits together, we have a final result of 90.
Thus, the solution to the addition problem is .
If we have 67 blocks in total, how many blocks will remain if we remove 5 tens and 4 ones?
Writing numbers in aligned columns helps you add the correct place values together! Units go with units (6+4) and tens go with tens (6+2+1).
Carrying means when a column adds up to 10 or more, you write the units digit in that column and move the tens digit to the next column left. Like 6+4=10, so write 0 and carry the 1.
It's possible but much harder! Adding from right to left (units first) makes carrying easier to track and reduces mistakes.
Write the small carried number above the tens column as a reminder! Then add all three numbers: 6 + 2 + 1 = 9.
Handle one column at a time from right to left. Carry from units to tens, then if tens column sums ≥ 10, carry to hundreds column.
