Sorry if I’m in the incorrect forum, but I’m new here 
I would need a function “multiplication” which returns the product of
her parametres “a” and “b”.
Can anybody help me please?

def mult(a,b)
res=0
while true
return(res) if b<=0
res=res+a
b=b-1
end
end
p mult 7,7
def add(a,b)
sa=’-’*a
sb=’-’*b
return “#{sa}#{sb}”.size
end
def multiplication(a,b)
a*b
end
Thanks that helped me!!

Ah, I love this. This is by far the best answer to the question.

p s( add(’----’,’–’) )
p s( add n(22), n(33) )
p s( moin n(22), n(1) )
