There are several valid forms to indicate multiplication, although some are used specificially for functions that are not simple integers.Multiply : the letter x, not as a variable (e.g. 3 x 5 = 15)Dot Product : (e.g. 3 . 5) -- often represented in ASCII by the asterisk (3 * 5)Multiple of variable (e.g. 2x, 3x)Multiplication is also indicated by parentheses and brackets, indicating successive sequences of operations, such as(3x-2)(x-1)[x(x-2)](x-1)
Size of variables
The symbol that you describe seems to be the greek letter Phi. It is normally used to indicate a variable that is an angle, just as x is used to indicate a variable that is a numeric quantity.
Yes, but the relationship need not be causal.
That refers to any symbol used to indicate some calculation. Here are some examples:+, -, *, / (for addition, subtraction, multiplication, division) ++, -- (to add or subtract one) (or), && (and)
Because if you did not combine them then you would have only one number: the number 1. You would not have 2 which is 1+1 and similarly no larger positive integers. Nor would you have negative integers which are obtained by subtraction. There would be no other rational numbers which are obtained by division. All in all, arithmetic would be pretty much useless.
(X) or X but with a bar above it to indicate multiplication by a thousand and numerals in brackets also indicate multiplication by a thousand.
NoRestate the question: When using the order of operations to evaluate an expression would you always do multiplication before division?If this is not your question, please clarify and ask the question again. :-)No. Unless parentheses or other grouping symbols indicate otherwise, you do multiplication and division in order from left to right.
Perform the indicated multiplication.
You can indicate addition by using it's sign "+" or saying add/plus.
There are several words used to indicate subtraction. Minus, deducted, subtracted from, decreased by, less than.
A ratio can indicate division. If you have a ratio, x:y, then it can be thought of as x/y.
MLCCLXXXImproved answer:(V)CCLXXX or VCCLXXX but with a horizontal line above the numeral V to indicate multiplication by a thousand.Numerals in brackets also indicate multiplication by a thousand.
(V) and (M) or V and M but with an horizontal line above the numerals to indicate multiplication by a thousand. Numerals in brackets also indicate multiplication by a thousand.
