My math calculation wont allow me to pass. WHY?


#1

4**2 = 16
I thought this was the most simplest thing to do but it says syntax error


#2

The thing is to let the computer do the computation:

4 ** 2

is an expression that will yield the value, 16. We could write it as a statement,

puts 4 ** 2           # 16

or assign it to a variable,

four_squared = 4 ** 2
puts four_squared     # 16
