Welcome to Android Central.

I'm no math genius but I don't see what the problem is. The answer is 9. Please correct me if I'm wrong. Thanks. - 08-08-2017, 09:26 PMMooncattRe: My android calculator shows 6÷2 (2+1)=9.
The order of operations ranks multiplication and division on the same level. Same goes for addition and subtraction. When you have both in an equation like this, you run them left to right. So:

6÷2x(2+1)=

6÷2x3=

(6÷2)x3=

3x3=9

So your calculator is correct, though I think I have seen at least one physical calculator get the order of operations wrong. For more info http://www.purplemath.com/modules/orderops.htm - 08-09-2017, 06:11 AMbelodionRe: My android calculator shows 6÷2 (2+1)=9.
I bet the answer is 1😠.

Whether it's 1 or 9, these things are very annoying, because there should be no possible room for doubt. Mathematicians must improve things accordingly😡. - 08-09-2017, 08:57 AMTim1954Re: My android calculator shows 6÷2 (2+1)=9.
It's 42.....

Values inside parentheses are evaluated before anything else, so 2+1=3. Then 6/2=3 * 3=9.

2(2+1) is the same as 2x(2+1) - 08-09-2017, 12:27 PMMooncattRe: My android calculator shows 6÷2 (2+1)=9.

*then*the addition. But that's not what's indicated by 6÷2 (2+1).

Remember - My Dear Aunt Sally - Multiplication, Division, Addition, Subtraction, but exponentiation before any of them and calculations inside parentheses are done before being used outside the parentheses. - 08-09-2017, 02:01 PMManiacJoeRe: My android calculator shows 6÷2 (2+1)=9.

My LG G4 calculator automatically puts in the multiply operator between the 2 and ( thus solving the ambiguity, but not necessarily solving it correctly. - 08-09-2017, 10:04 PManon(9602380)Re: My android calculator shows 6÷2 (2+1)=9.
Well there sure are some smarty pants in this crowd! :D
