What does a decimal point mean in a formula?

Question

The formula is;

(1 + C) . T
H = -------------
T
C + ----
D

I am okay with working it out other than the decimal point before the T in the formula. Can anyone tell me what it means, and maybe an example;

So if: D = 50
T = 1.5
C = 0.09

What does H equal.

Thanks

Answer 1

It means multiply.

Answer 2

A dot is sometimes used to mean multiply.
For example, a formula such as K = 5x² (y + 3) may, in some text books, be shown as K = 5x² . (y + 3)

Answer 3

ummmm, i'm only in algebra, but maybe it's a typo and is supposed to be a multiplication sign? because i know that after algebra, a dot is used to represent multiplication instead of an "x."

Otherwise, it could be apart of the formula. as in the integer is (1+C) and the decimal point is a decimal point and T is the tenths/hundreths/thousandths, etc...

Answer 4

The point in a number string indicates the point at which the
whole number becomes a part of a number.Therefore I assume
that bracketed (1+C) is more than T.
I might of course be speaking in the plural and spherical !!

Answer 5

It means multiply in this case, if you used the normal "x" symbol then it could be read as another term in the equation instead of an operator.

Answer 6

. = multiplied by. I never understand why people make things overcomplicated... wouldn't it be simpler to put a little "x" instead? =P

As you say, after getting the "." right, the rest of the equation is easy...

(1 + 0.09) x 1.5

However, I'm not really sure where D fits into the equation...

Answer 7

In a formula it is equivalent to multiply.

e.g. T.D means T*D

Answer 8

It's another way of saying "multiplied by."
