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.
