  12. Multiplication What functions do we need: 1. addNum(n1, n2) – two integers as input, output is the sum 2. shilfLeft(n, k) – an integer n and a shift number k, output is n multiplied by 10 raised to power k 3. multiplyLine(n, d) – an integer n and a digit d as input, output is n times d.

  13. Multiplication function number = multiplyNum(n1, n2); number = []; k=0; % line multiply shifts k position for i=length(n2):-1:1 number = addNum(number, shiftLeft(multiplyLine(n1,n2(i)),k)); k = k+1; end end
