We aim to solve minus using vertical subtraction.
First, align the numbers by their place value:
Step 1: Start from the rightmost digit (units place).
Units: : Since is less than , we need to borrow.
Borrow from the tens place:
The in the tens becomes (after borrowing 1), making the units place .
So, .
Step 2: Move to the tens place now.
Tens: : Borrow again because is less than .
Borrow from the hundreds place:
The in the hundreds becomes , turning the tens into .
So, .
Step 3: Now the hundreds place.
Hundreds: (Simple subtraction, no borrowing needed).
Step 4: Finally, the thousands place, which is direct.
Thousands: .
Thus, after all stages of subtraction, the result is:
Therefore, the solution to the subtraction problem is .
5585
\( \begin{aligned} &105 \\ -& \\ &~~~~3 \\ &\underline{\phantom{776}} & \\ \end{aligned} \)
No problem! Just borrow one column at a time from right to left. In this problem, we borrowed twice - once from tens to units, then from hundreds to tens.
We start from the units place because borrowing affects the column to the left. Working left to right would mean constantly changing numbers you've already calculated!
The digit you borrow from gets 1 smaller, and the digit you borrow to gets 10 bigger. Think: "I'm taking 1 ten and making it 10 ones."
Use estimation to check! is close to , so 5585 makes sense.
Yes! Try counting up from 178 to 5763. You should count up exactly 5585 steps, confirming your subtraction is correct.
