Description:

We want to write calculations using functions and get the results. Let's have a look at some examples:

seven(times(five)) # must return 35
four(plus(nine)) # must return 13
eight(minus(three)) # must return 5
six(divided_by(two)) # must return 3

Requirements:

  • There must be a function for each number from 0 ("zero") to 9 ("nine")
  • There must be a function for each of the following mathematical operations: plus, minus, times, dividedBy (divided_by in Ruby)
  • Each calculation consist of exactly one operation and two numbers
  • The most outer function represents the left operand, the most inner function represents the right operand
