How do you figure this problem out I am trying to help my son with his homework but can't figure out how to solve problem.

18+9x(5+4)divide 3-5

you manage to use + and x, but can't manage / ?

18+9x(5+4)/3-5
18+9x9/3-5
18+81/3-5
18+27-5
...
or
18+9x(5+4)/3-5
18+9x(9/3)-5
18+9x3-5
18+27-5
...

To solve this problem, we can use the Order of Operations, also known as PEMDAS. PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

Let's break down the problem step by step:

1. First, let's solve the expression inside the parentheses: (5+4) = 9.

2. Next, we'll perform the multiplication: 9 times 9 = 81.

3. Now, let's calculate the division: 3 divided by 5 = 0.6.

4. Lastly, we'll perform the addition: 18 plus 81 = 99.

So, the solution to the problem is 99.

To check your work, you can use a calculator or go through the steps again to see if you get the same result. Remember to always follow the order of operations to avoid any errors.
