Now, let's look at a sample problem to help you understand the PEMDAS rule better: You might be tempted to solve this math problem left to right, but that would result in the wrong answer! The first is where you get an exponent inside a bracketed part of the calculation, such as: 25 + (5 8 2 + 7) Although brackets theoretically take precedence over orders, within the bracketed part of the sum, the exponent takes priority over everything else so we resolve that first. Simplify \(\left[ {25 3\left( {6 + 1} \right)} \right] \div 4 + 9.\)Ans:The given expression is \(\left[ {25 3\left( {6 + 1} \right)} \right] \div 4 + 9.\)We will start solving inside the round bracket, i.e., \(\left( {6 + 1} \right) = 7\)Next, multiply \(3\left( 7 \right)\;\) or \(37=21\)Now, \(\left[ {25 21} \right] \div 4 + 9\)There is one bracket left, i.e., \(\left[ {25 21} \right] = 4\)After \(B\) and \(O,D\) comes.Hence, \(44=1\)Lastly, \(1+9=10\)Hence, the required answer is \(10\) after simplifying the expression.
