Answer 2

Solving the Expression

To solve the expression а - 3, we need to find the two last terms and enclose them in parentheses, placing a plus sign before the parentheses and a minus sign before the second term.

So, the expression can be written as: а + (-3).

This notation allows us to clearly indicate the operation to be performed on the second term.
