Greetings my friend @ubongudofot

I have come across this dilemma today, the answer is relatively easy when you know the capability of calculators, well, it turns out that for any mathematical operation you must follow an order of solution.

First you solve the parentheses, second the exponents, third the multiplications and divisions (from left to right). This order is not generated by some simple calculators, so it may result in an error in the calculation).

Technically you are absolutely correct, of course, those orders need to be observed to have the correct answer. ...

However, the answer I am looking for is far from this.😃

But let me understand one thing straight from you now. ..., do you agree with 9 being the correct answer?

It is not correct to say that the result is 9 when it is directly influencing the parenthesis, i.e., first we must perform the operation 2 (2+1), this can be solved as follows: (2x2 + 2x1) = 6 or 2(3)= 6. After we have this we are going to relate it with the 6, what before was [ 6 / 2(2+1)]; knowing that 2(2+1) = 6, then this is 6 / 6, therefore it is equal to 1.

You are right..., and thanks for the explanation.

9 is correct...!

However, it's also possible that if you click that on your calculator...it will give you 1

Why..?

Most Scientific Calculator doesn't understand parenthesis..., you have to change the operation first...before you qork with.

Also, if you look closely at the calculator, you will notice an M at the top, which means that ...likely the calculator result has been stored...😊

A mathematical result cannot be considered correct, just because you know where the flaw is, for sure you could be flunked if you don't know that the calculator is not useful to perform that kind of calculations.

Thats right....😄. Sometimes its trickish..
