9*9*9=729

What kind of mathematics is this called


Thank you

[Mamyalynne]

Multiplication.

[sanmac]

I'm sort of old school...Has x been replaced by *?

[bobbinwales]

Multiplying is * on Excel spreadsheet

[sanmac]

Ah, OK, thanks, Bobb.

[bobbinwales]

Why you asking degreen?

[jourdain2]

Common sense? I failed maths GCE 1st time, but looked at that and saw a simple multiplication. Trouble is that modern minds keep on wanting to change things. 9x9x9 would have been easily comprehensible. Senseless, to me, to lose the 'x' sign.

[Captain2]

In this case it is 9 cubed. Is cubing an acceptable mathematical function?

[sunny-dave]

That would be written 9^3 though, Captain2

[bobbinwales]

or 9³
9^3 is how you show it on Excel

[Captain2]

Same end result though SD? I'm only playing with names; hopefully, although I doubt it, degreen will enlighten us further.

[Mamyalynne]

I just thought I was being logical.

[Captain2]

Been no mention of Excel, bobb.

[THECORBYLOON]

DAVE, it would normally be shown as 9³, your version is what like it would be in an excel spreadsheet.

[Captain2]

Mamya,you are more than likely correct. I'm more amazed that degreen didn't recognise it.

[bobbinwales]

//Been no mention of Excel, bobb.//

not by degreen but several post's have used excel notation here

[sunny-dave]

Since the OP was in Excelspeak, it seemed logical to express cubing the same way - I agree that the superscripted ³ is the more usual way in non-spreadsheet usage.

[Captain2]

//not by degreen but several post's have used excel notation here//


at the time of my post, bobb, just your goodself.

[bobbinwales]

...And degreen and sunnydave with his9^3...but it would help to know what degrene is asking for

[THECORBYLOON]

I've seen ×,x and * used on various sites, I suppose it depends on the context and what the writer uses most often or what the style-guide dictates.

Mamy gave the answer in the very first post. There's no issue here. Multiplication (aka timesing) can be indicated by different notations, e.g. * or x or X or .
End of.
