A big problem of MS and older calculator in solving problem of math

There are some mathematical problems which are easy to solve without any calculator . But if someone uses a calculator he may find that the 2 answer may not be the same. Have you been through this kind of problem ? Try the bellow problem.

Can you say what is the answer of 10/2(2+3)? Is it 1 or is it 25?

If you have solve this problem you will find that this problem's solution may be 1 or 25.

I would recommend you to use a Scientific Calculator for solving this problem. Some of you will get 1 or some of you will get 25 as the answer of this problem. The answer will depend on what calculator you are using. If you are using 991MS,570MS,100MS or lower calculator the answer will be 1. But if you are using ES and the later versions of ES calculator the answer will be 25. There are some ES calculator where I have found the answer is 1. I have tried this problem in Microsoft Mathematics, there the answer was 25. In google calculator it was also 25.

So, what answer should I take? What is the right answer? Why?

I am telling you that the right answer is 25. Because of a rule in mathematics. Every problem must be solved from the Left hand side so 25 is the correct answer. In the previous versions of ES calculator this rule was not include. So the answer of ES and MS calculators are different. Google calculator and Microsoft Mathematics are updated and have a very good mathematical engine which help this software to solve problem like this. So they also give the right answer.

To get Microsoft mathematics just Click Here. This is the official website of Microsoft and you will find both 86x and 64x version of Mathematics mathematics.
