```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE, message = FALSE, warning = FALSE)
```

Store results in named objects.

```{r}
result <- 5 + 3
result
print(result)

daejin <- "instructor"
daejin
class(result)
class(sqrt)
```

**Interpret:** `result` is a number; `daejin` is text (`character`). `class()` tells you the type.
