# Find Sum, Mean and Product of Vector in R Programming

In this example, you will learn to find sum, mean and product of vector elements using built-in functions.

Similarly, `mean()` and `prod()` functions can be used to find the mean and product of the terms.

## Example: Vector Elements Arithmetic

``````> sum(2,7,5)
[1] 14
> x
[1]  2 NA  3  1  4
> sum(x)    # if any element is NA or NaN, result is NA or NaN
[1] NA
> sum(x, na.rm=TRUE)    # this way we can ignore NA and NaN values
[1] 10
> mean(x, na.rm=TRUE)
[1] 2.5
> prod(x, na.rm=TRUE)
[1] 24
``````

Whenever a vector contains `NA` (Not Available) or `NaN` (Not a Number), functions such as `sum()``mean()``prod()` etc. produce `NA` or `NaN` respectively.

In order to ignore such values, we pass in the argument `na.rm = TRUE`.
