How about getting this one right? 20/4(3+2) is equal to 1 due to distribution rules. Which your calculator does NOT properly follow.

**How about... you get this one right! ....**

About every two years, usually during an odd year, some idiot posts a simple expression with a wrong answer for its simplification and resolution to a numerical result. The same idiot also claims the calculator does not solve it correctly because it fails to follow the order of operations [PEMDAS or BIDMAS] correctly.

**This year, you are the idiot!**

The expression, as presented, equals (25) not one (1).

If by “distribution rules” you mean __Arithmetic Order of Operation Hierarchy__, then this calculator follows all (except for one*) of them, including the exceptions for **variables** usage, where *Implicit multiplication of variables takes precedents over division – a formally adopted exception, dating back to the 1968 mathematical society convention that included updates on mathematical order of operations hierarchy.*

As for your brain-dead expression, the calculator correctly resolves this to (25).

20/4(3+2) = 25 | This is correct for __Arithmetic Order of Operation Hierarchy__

----------

Note: by using a variable, then this resolves to one (1). This makes use of the exceptions for **implicitly multiplied** **variables before division **(described above**). **

x=4; 20/(x)(3+2) = 1 Though the parenthetical operation of (3+2) is not a variable it’s treated as one because of the variable preceding it and the implicit multiplication.

Also, by placing parenthesis around the (4), the calculator will use the variable-exception rule.

**20/(4)(3+2) = 1** Again, note that multiplication is ** implied** between the parenthetical operations.

[It’s also notable that when math is resolved or solved electronically, parenthetical operations are treated as variables in the registers.]

If the multiplication is made ** explicit** with a

**20/(4)*(3+2) = 25** ... the operations revert back to standard PEMDAS.

**This matches the answer you claim is correct, but ...**

**Your expression does not have a variable, so the **

**Additional notes:**

***This calculator’s exception for **__Arithmetic Order of Operation____ Hierarchy__

__Formal operation__**: Stacked powers **(aka: Power Towers) **are (exponentially) multiplied from the right to left (from the top down), and the resultant product becomes the EXPONENT to the base number.**

For this calculator, the Arithmetic Order of Operation Hierarchy is __not__ followed for Stacked Powers. The web2.0calc calculator resolves this from the left to right or ascending order, where the resultant product becomes the BASE of the next exponent. This operation is clearly defined in the *interpretation space*, above the calculator.

**Generally, power-towers are used in advanced, theoretical mathematics. For the majority of occasions where the construction of a power-tower occurs in an equation for the physical sciences, the ascending method is almost always used for its resolution (the descending method is rarely used). This is probably why Herr Mossow elected to code the calculator with the ascending method as the default ****operation****. This calculator, which is actually a computational engine, is orientated toward the **physical sciences, which is why it’s referenced as a Scientific Calculator.
