Answer 2

Hi there! I'll help you out.

We are asked to simplify the following expression:

`\longmapsto\quad\bf{20/2-8/4}`

The way we'll approach this problem is we'll use PEMDAS.

PEMDAS stands for: Parentheses, exponents, multiplication, division, addition, and subtraction.

As you can see, we have several operations in this problem.

According to PEMDAS, division comes first:

• 
  `\sf{20/2=\boxed{\sf{10}}`
• 
  `\sf{8/4=\boxed{\sf{2}}`

We now have:

• 
  `\sf{10-4}`

All we need to do is subtract:

• 
  `\sf{6}`

Therefore, the answer is 6.
