'''6÷2(1+2) == 6÷(2*(1+2))'''
Other calculators, including Google and Wolfram will simply strip the parenthesis and solve a different equation, 6÷2*(1+2)3.
This is because within the programming, the open parenthesis (bracketing) triggers a different function within the programming, an open parenthesis tells the compiler to find the innermost parenthesized term and work outwards. Thus to get the correct answer from inferior calculators the input must be formalized with correct bracketing. I.e. 6÷(2*(1+2))
