Use the PEMDAS method.

PEMDAS stands for:

Parentheses
Exponents
Multiplication
Division
Addition
Subtraction

Let's go through each:

Parentheses

We have one, #(4+1)#, which equals #5#. This gives us #6*7-3*5#.

Exponents

None.

Multiplication

We have two, 67 and 35. #6*7=42# and #3*5=15#. This gives us 42-15.

From here, all we need to do is subtract 15 from 42, which gives us #27#.
