Calculation of Remaining Pages to Type

To calculate the remaining pages to type, we can use the information provided. The manuscript contains "а" pages, and on the first day, the operator typed three-fifths of the entire manuscript, while on the second day, the operator typed minus one-fourth of the entire manuscript.

Let's calculate the remaining pages to type step by step:

1. Total Pages in the Manuscript (a): - The total number of pages in the manuscript is denoted as "a".

2. Pages Typed on the First Day: - The operator typed three-fifths of the entire manuscript on the first day. - This can be calculated as 3/5 * a.

3. Pages Typed on the Second Day: - The operator typed minus one-fourth of the entire manuscript on the second day. - This can be calculated as -1/4 * a.

4. Remaining Pages to Type: - The remaining pages to type can be calculated as the difference between the total pages and the pages typed on the first and second days.

Let's calculate the remaining pages to type using the given information.

Calculation

The remaining pages to type can be calculated as follows: - Remaining Pages = Total Pages - (Pages Typed on First Day + Pages Typed on Second Day)

Result

The operator has a - (3/5 * a) - (-1/4 * a) pages remaining to type.

Final Answer

The operator has a - (3/5 * a) - (-1/4 * a) pages remaining to type.
