I'm still trying to figure out how this became a thing on the internet years ago?

I had a calculator once in the 80s that worked right as far as dividing by 0...

If you put in 32/0 and pressed = It said 0 which is the right answer!!! (Most give you an error .. Including the one on my computer)

^ Dude: It IS an error. What times zero will give you 32? Nothing. That's because any number times zero is zero.

Furthermore, if you try to do it in Excel, the error message (starting with a hashtag symbol) DIV/0 will appear.

The old calculators will say 0 with an E (for error) on the top right corner, and it'll be frozen where you can't do anything unless you turn it off or cancel it.

That's right, and you can clear it by pressing "C" (for clear).

It'll also display zero with an E if you try to take the square root of a negative number, or do a calculation with a result that has more digits than the display can hold (i.e., an overflow).

There are MULTIPLE reasons why you can't divide by zero. From what I've learned in class over the years. Let me break it down.

Take 8 blocks and divide it into 4 sections, you get 2 blocks each. Take 18 blocks and divide it into 6 sections, you get 3 blocks each. Take 4 blocks and pretend that it's 1/2 of a section, then you get 8 blocks in all. Take 4 blocks and pretend that it's 1/8 of a section, then you get 32 blocks in all. Take 8 blocks and divide it into 0 sections...... that's impossible.

8/0 = 0 ?

3/0 = 0 ?

0 * 0 =/=3

0* 0 =/=8

3=/=8

doesn't make any sense here

neither does this.

8x0=0

3x0=0

5x0=0

0/0 = 3, 8, 5, 4, 7 ????

Another thing using the subtraction rule, as multiplication means adding the same number bunch of times, while division means subtracting the same number a bunch of times until you get 0.

21/7 = 3 means 21-

88/11=8 means 88-

5/0.5=10 means 5-

23/0 means 23-0=23-0=23-0=23-0=23-0=23-0=23-0=23-0...... you're subtracting zero forever while staying at 23, so you'll never get an answer, it's going infinitely, which proves that this is undefined.

Now going by calculus, this is another reason why division by zero doesn't make sense. You divide very big numbers, you get very small numbers. You divide very small numbers, you get very big numbers. Now you might think that anything divided by zero is infinity, but NOPE, there's another problem explained here.

10/5=2

10/2=5

10/1=10

10/.1=100

10/.001=10000

10/.00000000.....00001=1000000000.....0000

10/0 = ∞

10/-5=-2

10/-2=-5

10/-1=-10

10/-.1=-100

10/-.001=-10000

10/-.00000000.....00001=-1000000.....0000000

10/0 = -∞

OOPS, last time I checked, ∞ =/= -∞

Yep, that just too much chaos for division by zero to be possible. If division by zero was ACTUALLY POSSIBLE in the universe, it would have to be possible time travel, a black hole at the singularity, entering the spiritual world instantly instead of waiting until after we die. I don't want to even know. ;D

^ I actually knew all that, given my vast knowledge of mathematics.

Additionally, while nonzero/0 is always undefined, 0/0 is an indeterminate form, which arises in higher mathematics such as calculus when trying to find a limit of a rational expression. It could be any value, depending on the nature of the expression, but it could also be undefined. In fact, there is a complete explanation of this concept on

Let me work this out...

Ah man!! (Maybe I didnt see the E)

Did you partake in making words from the numbers when turning the calculator upside down?

I remember that.

For example, if you enter 1 minus 0.2266, the answer will be 0.7734, which reads hELLO when turned upside down (the word "hello").

certain numbers that you would type into the calculator, upside down would become a word.

I know, and I was just giving an example, 0.7734 is HELLO.

I remember all that also :)
