6/2(1+2)=? The answer is 9.
The BIDMAS or PEMDAS Rule says that brackets must be done first.
1) (1+2)=3
Then you do multiplication or division first since it is the next step in the rules that apply to this equation.
Many are confused as to which one they are supposed to do because they give a different answer. However, all equations are solved by left-to-right if you must choose from times and divide, or plus and minus.
2)6/2=3
Now the equation is: 3(3)
This means multiply.
3)3*3=9
The equation is solved.

4 + (2/32) + 1
x[x+1] squared Simplified is, to my knowledge, x squared plus ( x + 1) squared
Multiplication and division first, addition and subtraction second. Without brackets, that equation equals 2.
3(x + 1)(x + 3)
It does. Follow order of operations (BEDMAS): (2+10)/(2x6), brackets first (12)/(12), no exponents 12/12 = 1 by division
