To correctly add 245 + 99, let’s break it down step by step using one of the methods described:
1. Start with 245.
2. Add 100: 245 + 100 = 345.
3. Now, since we need to add 99 (which is 100 – 1), we can subtract 1: 345 – 1 = 344.
So, the correct calculation is:
245 + 99 = 344.
In this approach, we first round up to the nearest hundred to make the addition easier, then adjust by subtracting the 1 we added extra.
