3*6-4/5

To solve this expression, we need to follow the order of operations, which is known as PEMDAS (Parentheses, Exponents, Multiplication and Division [from left to right], Addition and Subtraction [from left to right]).

In this case, we'll start by evaluating the multiplication:

3 * 6 = 18

Then, we move on to the division:

4 / 5 = 0.8

Now, we subtract the result of the division from the result of the multiplication:

18 - 0.8 = 17.2

Therefore, the answer to 3 * 6 - 4 / 5 is 17.2.
