When is try to implement the multiply test, the first test for multiply two arguments pass but for multiple arguments fail

this is the calculator_spec.rb

# Extra Credit Test-Driving Bonus:

# once the above tests pass,

# write tests and code for the following:

describe “multiply” do

it “multiplies two numbers” do

expect(multiply(2, 2)).to eq(4)

end

it “multiplies several numbers” do

expect(multiply(2, 2, 2)).to eq(8)

end

end

this is the function definition

def multiply(x, y)

x * y

end
