Think of the problem as money.
1. = $1.00
Take 99 cents away from a dollar and you have 1 cent left.
Here's how you can do it step by step:
1. Start by aligning the decimal points:
1.00000
- 0.98765
2. Beginning from the rightmost digit, subtract the corresponding digits:
1.00000
- 0.98765
________
0.01235
The answer comes out to be 0.01235, not 1.01235 as you initially thought. This is because the digits after the decimal point have a greater value than the digits before the decimal point. Hence, subtracting 0.98765 from 1 gives you a result that is less than 1. The correct result is 0.01235.
If you used a calculator and obtained the answer of 0.01235, then that is the correct result. Calculators are programmed to perform arithmetic operations accurately, so you can trust the answer it provides.
