Question

What are two ways can you write 4 - n as an algebraic expression?​

Answer 1

Answer: 4 + (-n) and -n+4

==========================================================

Step-by-step explanation:

Adding a negative is the same as subtracting. For example, 10-7 = 10+(-7)

So that's why 4-n is the same as 4 + (-n)

---------

Then we go from 4 + (-n) to -n+4 because we can add two items in any order.

Example: 2+3 = 3+2 = 5
