Math term i can't remeber

[Maarchk]

My prof. keeps saying the reciprocal of .7 is .3.
I know thats wrong. the reciprocal of .7 is 1 over .7 which is a number greater then 1.

what is the term for 1 - X where X is a decimal, so you get another decimal?

Class lasts till 10 pm tonight, pac time.

All help is appreciated.. I checked google and could not find it.

Thanks,
Mark

Sounds like a decimal compliment/suplement but I'm really just guessing.

Unit compliment... :naughty:

uhm subtraction? x is a decimal. the result is a decimal. 1 - X = ?
1 - 0.7 = 0.3

I don't know. Where are the math nerds??

I don't believe there is any special term for what you're decscribing. There is a term called the additive inverse which is basically -X, but that's not what you're describing. We can call it a Maarchkism from now on!

Ummm...the reciprical of .7 is definately NOT .3.

.7=7/10

reciprical of that is 10/7 ~ 1.42

.3 is just that

and 1.42 and .3 do not equal here....:)

Uh...what school is this...you might want to change schools if a COLLEGE prof can't get reciprocal right...

call him on it before or after class. you probably aren't the only one who is confused by it
