Solve the Expression: 95-0.94-0 Step by Step

Q: Why doesn't subtracting zero change the number?

Zero is the additive identity, which means adding or subtracting it doesn't change any value. Think of it like having 95 apples and taking away 0 apples - you still have 95!

Q: How do I compare two numbers quickly?

Look at the place values from left to right. Since both numbers have the same tens place (9), compare the ones place: 5 > 4, so $ 95 > 94 $.

Q: What if the numbers were much larger?

The same rules apply! Subtracting zero never changes a number, no matter how big or small it is. Then compare digit by digit from left to right.

Q: Could the answer ever be equal?

Only if both expressions simplified to the same number. Since $ 95-0 = 95 $ and $ 94-0 = 94 $, and 95 ≠ 94, the answer is definitely greater than (>).

Q: What does the symbol > mean exactly?

The symbol > means "greater than". Think of it like a hungry mouth that always wants to eat the bigger number: 95 > 94 means 95 is greater than 94.

Understand the problem

$95-0?94-0$

Step-by-step solution

To solve this problem, we will follow these steps:

Step 1: Evaluate the expression $95 - 0$ .
Step 2: Evaluate the expression $94 - 0$ .
Step 3: Compare the results of both evaluations.

Let's work through these steps:
Step 1: Evaluate $95 - 0$ . Since subtracting zero does not change the number, $95 - 0 = 95$ .
Step 2: Evaluate $94 - 0$ . Similarly, $94 - 0 = 94$ .
Step 3: Compare the results: $95$ and $94$ . Clearly, $95$ is greater than $94$ .

Therefore, the correct comparison between $95 - 0$ and $94 - 0$ is $\mathbf{>}$ .

Final Answer

Key Points to Remember

Essential concepts to master this topic

Zero Rule: Subtracting zero from any number leaves it unchanged
Technique: Simplify 95-0=95 and 94-0=94, then compare values
Check: Verify 95 > 94 is true since 95 is one more than 94 ✓

Common Mistakes

Avoid these frequent errors

Thinking subtraction by zero changes the number
Don't assume 95-0 equals something other than 95! This leads to incorrect comparisons and wrong answers. Always remember that subtracting zero never changes a number's value.
