How do you know weather to add or subtract when you use the distributive property to multiply

Step-by-step explanation:

To answer your question, I will give two examples.

First and foremost, distributive property of a system of linear expression in algebra allows us to simply an expression by following the rule of expansion.

now, to know whether to add, lets take a look at this example;

                               a(b+c) = ab + bc

simplifying the expression above gives  ab + bc

this shows that when you are using the distributive property to multiply an addition, you will add the result.

on the other hand, lets look at ;       a(b-c) = ab - bc

the result shows that when you are using the distributive property to multiply a difference of variables or number, you will subtract the result.
