Does a calculator always give the correct answer ?

[TheBox]

Hello ,

Calculator 2/2+1=2

Me 2/2+1=2*1+1=3

A calculator does not recognise that 2/2 creates 2 sets of 1 . In the equation there is no subtraction but the calculator gives the answer of 2 subtracting a value .


Lets look at this in a reality way rather than just conceptual .

2 apples divided by 2 boxes equals 1 apple per box plus 1 apple equals 3 apples in total !

If you "play out" your equations that you label as "Me". You have...

2=3=3

If a calculator always gives a right answer, is a subjective truth. You are right in saying that a calculator does not recognize what it is doing. It is only a program. But that program can be modified to lie. It would not now it. Math is an objective truth built on an agreed upon subjective truth. There are many base systems also. The best way to understand this is in division by zero. Is "undefined" or "error" really the right answer? It cant be because by definition these are not answers at all. The calculator is literally saying answer not known. Which of course is not an answer.

Please feel free to correct me on anything I have misunderstood.

Well , when you are a science type , you will always search for an answer . A calculator or even the human mind will conclude that 1/0 cannot be done . However , with a little more thought 1/0 can be achieved .

1 degrees Celsius / 0 degrees Celsius changes the parameters of the equation allowing the equation to be achieved .

Spatial volume playing the key role of the equation .

It is also more than a calculator does not recognise what it is doing . The programming of the calculator is human error demonstrating that humans do not really understand maths correctly .


Another typical example would be 1*0 !

A calculator and/or a human will give an answer of 1*0=0 but again when conceptual versus reality , the answer of 0 becomes incorrect .

In reality £1 * £0 =£1 because we have the starting primary dominator in our hand and no subtraction of the primary .

Please feel free to place £1 in your hand and do this equation !

No need! I agree whole heartedly! Units or "space" is the key. If you give abstract numbers an abstract unit. Just as concrete numbers have a concrete unit. Then division and multiplication by zero become possible. I have a thread called "The Unified Number". Posted in the section Other Advanced Math. It is directly dealing with this. Please check it out.
