Solving the Subtraction Problem: 394 Minus What Equals 153?
This is a simple subtraction problem that can be solved using a few different methods. The core question is: what number, when subtracted from 394, results in 153?
Here's how to solve it:
Method 1: Algebraic Approach
We can represent the unknown number with a variable, let's say 'x'. The problem can then be written as an equation:
394 - x = 153
To solve for 'x', we need to isolate it on one side of the equation. We can do this by subtracting 394 from both sides:
-x = 153 - 394
-x = -241
Now, multiply both sides by -1 to find the positive value of x:
x = 241
Therefore, 394 minus 241 equals 153.
Method 2: Direct Subtraction
Alternatively, you can solve this directly. Think of it as asking: "What is the difference between 394 and 153?" You can perform the subtraction:
394 - 153 = 241
This also confirms that the answer is 241.

H2: How do I solve subtraction problems?
Subtraction problems involve finding the difference between two numbers. You can use various methods, including:
- Direct subtraction: Subtracting the smaller number from the larger number.
- Algebraic approach: Using variables and equations to solve for an unknown.
- Number lines: Visualizing subtraction on a number line.
- Decomposition: Breaking down the numbers into smaller parts to simplify the subtraction. (Useful for larger numbers).
The best method depends on the complexity of the problem and your comfort level with different mathematical techniques.
H2: What are some common mistakes in subtraction?
Common mistakes include:
- Borrowing errors: Incorrectly borrowing from the next column when subtracting.
- Incorrect alignment: Not aligning the numbers properly according to their place value.
- Subtracting the larger number from the smaller number: Remember you can't subtract a larger number from a smaller number without resulting in a negative answer.
