Answer 3

These expressions involve basic arithmetic operations of addition (+) and subtraction (-) using the same variable "на" in each case. However, without knowing the specific values of "на" involved, it is not possible to determine the exact results of these expressions.

To illustrate with an example, let's say "на" represents the number 5. Then:

• "на + на" would equal 5 + 5 = 10
• "на - на" would equal 5 - 5 = 0
• "+ на -" is not a valid expression as it is missing a value or operation
• "- на -" is also not a valid expression as it is missing a value or operation

Therefore, the results of these expressions depend on the specific numerical value of "на" that is being used.
