Q1: What is the correct recursive definition of the multiplication?
A1: $(n+1) \cdot m = (n\cdot m) + m$
A2: $(n+1) \cdot m = n\cdot m $
A3: $(n+2) \cdot m = (n\cdot m) + m$
A4: $ n \cdot m = (n\cdot m) + m$
A5: $(n+1) \cdot m = (n\cdot m) + n$
Q2: What is the correct distributive law?
A1: $k \cdot (n+m) = (k\cdot n) + (k \cdot m)$
A2: $k \cdot (n \cdot m) = (k \cdot n) \cdot m $
A3: $ n \cdot m = m \cdot n$
A4: $ 0 \cdot m = 0 + m$
A5: $0 \cdot m = 0$
