Answer: -2.98
Step-by-step explanation:
1. Start by subtracting the whole numbers: 8 - 5 = 3.
2. Next, subtract the decimals: 0.02 - 0.98 = -0.96.
However, we need to be careful when subtracting decimals. In this case, 0.02 is smaller than 0.98, so the result will be negative.
To simplify the calculation, we can convert 0.98 to 0.02 by borrowing from the whole number.
Here's how:
- Take 1 from the 8, which becomes 7.
- Add 1 to the 0.02, which becomes 1.02.
- Now subtract: 7 - 1.02 = 5.98.
So the final answer is 3 - 5.98 = -2.98.
