Both Are very Correct

Reasons
I. Both are programmed with different algorithms to solve the same problem.
How
I. The Casio work with an algorithm or principle of BODMAS while The Android phone and other computers are programmed with an algorithm or operate with a principle of operator precedence.
How Does The Algorithm Work
With the above question here is the solution of bodmas and operator precedence solution.

I. BODMAS algorithm

6÷2(2+1) -First work is B "bracket"
6÷2(3) - second work is O "of"
6÷6 - third work is D "division"
Answer= 1.

II. OPERATOR PRECEDENCE algorithm
6/2(2+1) -first work is bracket, it has higher precedence than multiplication and division
6/2(3) -second work is division, because division and multiplication have the same number of precedence, therefore there is a rule that is applied to choose which one to apply first. The rule is left-to-right. Whenever two operators have the same number of precedence you work left-to-right.
3(3) -third work is multiplication
Answer= 9

Note: - I will advise, most especially students in secondary schools to use the one of the casio because that is what applies to bodmas which is used in secondary schools and University.
The one of Android phone is mostly used by computer science student.

In conclusion both the Casio and the Android Phone answer is correct.

You are telling me that an "Accountant" fit calculate my transaction balance, instead of my balance to show 900k, e go show 100k? No wonder Yoruba people usually rush to read Accountancy.

Which kain olodo b dis op.
Don't you know you're suppose to solve what's in the bracket first and multiply the outcome of the one outside the bracket with the one in the bracket.

6/2(2+1)
First solve what's in the bracket
6/2(3)
Then solve outside the bracket
6/2=3
Then you have
3(3)
Now you have to multiply to open the bracket in order to get your final answer which is 9.


It's just a basic 1 calculation and see as growns they yahn nonsense.

Go sku you no gree.
I bet you still depend on your phone calculator to do some basic calculations.

Every entity has their ways of solving problems.
That is why when you go to school you always find X but after graduation those who work in financial institutions they no longer find X rather plus and minus. Simple addition and subtraction, you pay in money to your bank account is an addition while you withdraw money from your bank account is a subtraction. So where does the irregularities in your account balance come from?

MyFlair:
Know you that 2*(2+1) is not exactly this samething as 2(2+1). In fact 2(2+1) is the result from 2*(2+1). So the calculator is correct mathematically. For instance, you can't say that 6÷2x is 3x.
The android app treated 6÷3(2+1) as 6÷2(2+1) as 6÷2*(2+1). And that's wrong. 6÷2(2+1) has two operands but 6÷2*(2+1) has three.

I disagree, most secondary school students don't know the nitty gritty of BODMAS. Bracket is not multiplication, and that's where the problem comes from.
