1. The problem is to find the result of the subtraction (+98) - (+88). 2. The formula for subtraction of integers is: $$a - b = a + (-b)$$ which means subtracting a number is the same as adding its opposite. 3. Applying the formula: $$+98 - (+88) = +98 + (-88)$$ 4. Now add the numbers: $$98 + (-88) = 98 - 88$$ 5. Simplify the subtraction: $$98 - 88 = 10$$ 6. Therefore, the answer is 10.
