You just need to remember the order that operations are to be performed.

2\(300-40\div5\) - [3\times 23 - (8-2\times3)]

Is that it?

Multiplication and division come before addition and subtraction. We're working within the brackets, so that is okay.

2\(300-8\) - [69 - (8-6)]

Now that there are only brackets to work with, we do what there is in brackets.

2\(292\) - [69 - 2]

And the last operations:

584 - 67

517

For the next one:

2\times600-8

Multiply first!

And for the last one:

2\times 277 -15

That's good! :)
