what is 0.1+0.2-0.3?

deepseek-r1-distill-qwen-7b: Alright, let's tackle this problem step by step. So, the question is: what is 0.1 + 0.2 - 0.3? Hmm, at first glance, it seems straightforward, but I want to make sure I do this correctly.

Okay, starting with adding 0.1 and 0.2. Let me visualize a number line in my head. If I have one-tenth and add two-tenths, that should give me three-tenths. So, 0.1 + 0.2 equals 0.3. That part seems simple enough.

Now, the next step is subtracting 0.3 from that sum. So, if I take 0.3 (which is the result of adding 0.1 and 0.2) and then subtract another 0.3, what do I get? Well, subtracting three-tenths from three-tenths should bring me back to zero.

Wait a second, let me double-check that. Sometimes with decimals, it's easy to make little mistakes. So, adding 0.1 and 0.2: 0.1 is like one dime, and 0.2 is two dimes. Together, that makes three dimes, which is 0.3. Then subtracting another three dimes would indeed leave me with zero.

Is there any chance I could have messed up the decimal places? Like, maybe thinking of them as whole numbers instead? Let's see: if I treated them as integers, 1 + 2 - 3 equals 0. So that still checks out.

Another way to look at it is by converting everything into fractions. 0.1 is 1/10, 0.2 is 2/10, and 0.3 is 3/10. Adding the first two gives me (1 + 2)/10 = 3/10, which is 0.3 again. Subtracting 3/10 from that leaves me with zero.

I think I'm pretty confident here. The operations are straightforward, and both methods—decimal addition and fraction conversion—lead to the same result. So, yeah, it looks like the answer should be zero.

The result of 0.1 + 0.2 - 0.3 is:

0

Step-by-Step Explanation:

Add 0.1 and 0.2: 0.1 + 0.2 = 0.3 Subtract 0.3 from the sum: 0.3 - 0.3 = 0 Therefore, the final answer is 0.
