+# [Return the first M multiples of N](https://www.codewars.com/kata/593c9175933500f33400003e)
+
+Implement a function, `multiples(m, n)`, which returns an array of the first `m` multiples of the real number `n`. Assume that `m` is a positive integer.
+
+Ex.
+
+```
+multiples(3, 5.0)
+```
+
+should return
+
+```
+[5.0, 10.0, 15.0]
+```
