One More PEMDAS ExampleThis example has two sets of grouping symbols: parentheses () and brackets []. When an expression has more than one set of grouping symbols, start with the innermost symbols and work out from there. In this case, we need to start with the 6 squared inside the inner parentheses. Once we simplify that, we need to keep simplifying what's inside the brackets next. This gives you 6 + 4[9].


A common mistake in the example above is to multiply the 3 and 6 together and then square it. Make sure to remember that exponents come before multiplication.
