I need help to increase the efficiency of this code :

global repeat

repeat=1

def main():

c=int(raw_input("How many numbers do you want to work? (Min. 2 Max. 3) "))

if c==2:

x=int(raw_input("Enter the first number to be worked "))

y=int(raw_input("Enter the second number to be worked "))

elif c==3:

x=int(raw_input("Enter the first number to be worked "))

y=int(raw_input("Enter the second number to be worked "))

z=int(raw_input("Enter the third number to be worked "))

else:

print "Invalid input.";raw_input("Press <enter> to close this window");exit()

p=int(raw_input("Do you want to divide, subtract, add or multiply these numbers? (1=divide, 2=subtract, 3=add, 4=multiply) "))

if p==1 and c==2:

print "The result is : ",x/y

repeat=int(raw_input("Do you want to calculate for more numbers? Yes=1 No=2 "))

if repeat==1:

main()

elif p==1 and c==3:

print "The result is : ",x/y/z

repeat=int(raw_input("Do you want to calculate for more numbers? Yes=1 No=2 "))

if repeat==1:

main()

elif p==2 and c==2:

print "The result is : ",x-y

repeat=int(raw_input("Do you want to calculate for more numbers? Yes=1 No=2 "))

if repeat==1:

main()

elif p==2 and c==3:

print "The result is : ",x-y-z

repeat=int(raw_input("Do you want to calculate for more numbers? Yes=1 No=2 "))

if repeat==1:

main()

elif p==3 and c==2:

print "The result is : ",x+y

repeat=int(raw_input("Do you want to calculate for more numbers? Yes=1 No=2 "))

if repeat==1:

main()

elif p==3 and c==3:

print "The result is : ",x+y+z

repeat=int(raw_input("Do you want to calculate for more numbers? Yes=1 No=2 "))

if repeat==1:

main()

elif p==4 and c==2:

print "The result is : ",x*y

repeat=int(raw_input("Do you want to calculate for more numbers? Yes=1 No=2 "))

if repeat==1:

main()

elif p==4 and c==3:

print "The result is : "+str(x*y*z)

repeat=int(raw_input("Do you want to calculate for more numbers? Yes=1 No=2 "))

if repeat==1:

main()

else:

repeat=int(raw_input("Invalid Input. Please read instructions properly. Would you like to try again? Yes=1 No=2 "))

if repeat==1:

main()

else:

exit()

main()

Is there any way to make it smaller? It does it's job, but I want it to look smaller, more efficient.
