The sum of 7 and 11 is If the product of a number and —7 is reduced by 3, the resulting number is 33 less than twice the opposite of that number.

These are called the natural numbers, or sometimes the counting numbers. The use of three dots at the end of the list is a common mathematical notation to indicate that the list keeps going forever. If the farmer does not have any sheep, then the number of sheep that the farmer owns is zero.

We call the set of natural numbers plus the number zero the whole numbers. About the Number Zero What is zero? Is it a number? How can the number of nothing be a number?

Is zero nothing, or is it something? When we write a number, we use only the ten numerals 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.

These numerals can stand for ones, tens, hundreds, or whatever depending on their position in the number. Think of it as an empty container, signifying that that place is empty.

For example, the number has 3 hundreds, no tens, and 2 ones. So is zero a number? The number zero obeys most of the same rules of arithmetic that ordinary numbers do, so we call it a number.

Note for math purists: In the strict axiomatic field development of the real numbers, both 0 and 1 are singled out for special treatment. Zero is the additive identity, because adding zero to a number does not change the number. Similarly, 1 is the multiplicative identity because multiplying a number by 1 does not change it.

Even more abstract than zero is the idea of negative numbers. If, in addition to not having any sheep, the farmer owes someone 3 sheep, you could say that the number of sheep that the farmer owns is negative 3.The definition says that a number is rational if you can write it in a form a/b where a and b are integers, and b is not ph-vs.comy all fractions are of that form, so fractions are rational numbers.

Terminating decimal numbers can also easily be written in that form: for example = 67/, = /, and so on. The task is to write a program to transform a decimal number into a fraction in lowest terms. It is not always possible to do this exactly. For instance, while rational numbers can be converted to decimal representation, some of them need an infinite number of digits to be represented exactly in decimal .

Rational numbers include natural numbers, whole numbers, and integers. They can all be written as ph-vs.comn is natural, whole, and an integer. Since it can also be written as the ratio or the fraction 16/1, it is also a rational number.

Jul 06, · You definitely can use IF's in a UDF. There are a few syntax errors, but main issue is that you need to move the @FinalMinutes to outside the IF as it needs to be returned from the main scope.
