34÷3+12÷3+2-6+9÷6+4+7
34/3+12/3+2-6+9/6+4+7
Remember PEMDAS:
11.33+4+2-6+1.66+4+7
The rest can be added together into a calculator (or by hand if you are not supposed to use one)
You have to follow the order of operations PEMDAS (parentheses, exponents, multiplication/division, addition/subtraction)
You do all the division first to be left with
11.33+4+2-6+1.5+4+7
Then you just go straight across adding and subtracting to get 23.83!
