Let's solve the basic vertical subtraction problem where we subtract 4 from 157 step by step:
Step 1: Write the numbers in a vertical format, ensuring to align them by place values.
Step 2: Perform subtraction starting from the rightmost digit (the ones place).
- Subtract 4 from 7 in the ones column, resulting in 3.
Step 3: Since the number being subtracted, 4, has no digit in the tens and hundreds places, bring down the remaining digits from 157. These are 5 in the tens place and 1 in the hundreds place.
Thus, the result of subtracting 4 from 157 is .
Among the options provided, choice 2 is the correct answer, which states 153.
Therefore, the solution to the problem is .
153
\( \begin{aligned} &97 \\ -& \\ &63 \\ &\underline{\phantom{776}} & \\ \end{aligned} \)\( \)
Aligning by place value ensures you're subtracting ones from ones, tens from tens, etc. Without proper alignment, you might subtract from the wrong digits!
Just bring down the remaining digits from the top number! In 157 - 4, the 1 and 5 have nothing to subtract from them, so they stay the same.
Use addition to check! Add your answer to the number you subtracted. If you get the original number back, you're right: ✓
Yes, always start from the ones place (rightmost column) and work your way left. This follows the standard subtraction algorithm and prevents errors.
In this problem, you don't need to borrow since 7 > 4. But when the top digit is smaller, you borrow from the next column to make subtraction possible!
