Do you want combinations or permutations? They're different things. A combination of n items taken m at a time, sometimes written "nCm", selects m items from a group of n without regard to order. A permutation of n items taken m at a time, sometimes written "nPm", selects m items from a group of m with regard to order.

Given six numbers, there are six combinations of one number, 15 combinations of two numbers, 20 combinations of three numbers, 15 combinations of four numbers, six combinations of five numbers, and one combination of six numbers.

Given six numbers, there are six permutations of one number, 30 permutations of two numbers, 120 permutations of three numbers, 360 permutations of four numbers, 720 permutations of five numbers, and 720 permutations of six numbers.

1and 5/7 ==1.7142 (5/7 to get decimal point=.7142)

+ 9 divided by minus 1.7142= minus 5.1688

using the maths laws of multiplication and division of numbers where + and - indicies are used +X+ =+ and + X - = - and - X- = +

you will find answers on the web maths pages

If there was a question it is not clear. I will show you what commutativity works. Whether that answers your lack of question remains to be seen.

Commutativity of multiplication (or the commutative property of multiplication) means that the order of the factors in a product does not affect the result. In other word, the order of factors is unimportant.

3*7+2 =7*3+2=23

2*7*3=2*3*7=7*2*3=7*3*2=3*2*7=3*7*2=42

Use the words: decimal part, not decimal fractin

**Any number whose decimal part is periodic (has a recurring pattern that repeats indefinitely) is equivalent to a rational number, IS a rational number**

0.345 345 345 ... =345/999=115/333

In the following screen captures, discard the last digit if it does not belong to a period. It is the effect of rounding up of the calculator

**Period is 345**

**Period is 1**

Period is**09**

Period is** 79**

In general, if you have a decimal part of the form 0.d_1 d_2 d_3....d_n d_1 d_2 d_3 ...d_n ... where d_1 is the first digit of the period, d_2 is the 2nd digit of the period, ..., d_n is the n-th digit (and the last one) of the period, then the fraction representation of

0.**d_1d_2...d_n** d_1d_2... d_n ...=(**d_1d_2...d_n**)/(99...9) where the number of 9's in the denominator is equal to the number of digits in the period.

Once the fraction is found, one should reduce it to its simplest form.

0, 1, 3, 6, 10, and 15. If you don't consider 0 to a triangular number then the next one is 21.

Using the 1515 as a fax machine is a pretty simple procedure if everything works right. All you have to do is hook a working phone line up to the phone jack on the back of the copier (the one labeled LINE, not TEL).

Why won't the fax work? If it is giving you an error message, what is the message?

If you are not getting a dial tone when faxing, unplug the fax from the phone line and plug a working phone in, and see if the phone gets a dial tone. If it doesn't, there is a problem with your phone line.

You can also try plugging the fax machine into another phone line. If the fax works on that line, then there may be a problem with the first line.

Are you having problems sending faxes or receiving them, or both?
