The Real Number System and Order of Operations Assignment

The Real Number System and Order of Operations - Assignment Example M stands for Multiplication and it takes the third precedence in the order of operations. Looking at this expression, 4 x 8 – 6 + 3, we multiply 8 by 4 to get 32, then add 6 to 3 to get 9. Subtracting 9 from 32 we get 23. S stands for subtraction. Any subtracting command is executed last when doing the sums. In our above expression, our last step was to subtract 9 from 32 where we got 23. The order in which the signs will follow each other is important and it determines the answer one gets. Following the correct steps and orders in life is very important. For science students, following the correct order of operations and steps would mean the difference between getting the desired results and getting a disaster in case the steps are mixed up. Take an example of the preparation of Potassium Hydroxide;- If for example a student interchanged the steps and put the potassium into the water bath then due to the high reactivity of potassium with water, an explosion would ensue. This just helps to illustrate the need to follow correct steps in real
