Use the PEMDAS method.

PEMDAS stands for:

Parentheses
Exponents
Multiplication
Division
Addition
Subtraction

In our equation, there are no parentheses or exponents, but there is a multiplication problem. Let's solve this:

#2*3=6#

We now have #36//4-6#.

Next up is division:

#36//4=9#

We now have #9-6#.

From here, simply subtract 6 from 9 to get our answer, #3#.

#3#

Always count the number of terms first. Each term must simplify to a single answer and only in the LAST step are they all added or subtracted.

Within each term, parentheses are done first.
Then do the strongest operations of Powers and roots,
Then multiplication and division,

You can work in any term independently of others.

=# color(blue)(9)color(red)(-6)#

=#3#
