Rem Multiplication
for y = 0 to max
for x = 0 to max
Prod[x+y]=Prod[x+y]+n1[x]*n2[y]
next x
next y

Rem Carying
for x = 0 to p-2
While Prod[x]>9
Prod[x]=Prod[x]-10
Prod[x+1]=Prod[x+1]+1
end While
next x

Rem Printing
for x = 0 to max
print n1[max-x];
next x
Print" x ";
for x = 0 to max
print n2[max-x];
next x
Print" = ";
p=p-1
for x = 0 to p
Print Prod[p-x];
next x
