Mighty Geometry Helper v1.0

Looks good, only think I would change is use float instead of int.
I was working on something similar, you beat me to it, so here what I had(This isnt finished, but no use in finishing it now )

Code:

class math:
    def add(self,a,b): print a + b
    def sub(self,a,b): print a - b
    def mul(self,a,b): print a * b
    def div(self,a,b): print a / b
    def slope(self,a,b,c,d): print (a - b) / (c - d)
    def triangle(self,b,h): print 0.5*b*h
    def rectangle(self,b,h): print b*h
    def circle(self,r): print 3.141592*(r*r)
math = math()
def area():
    print "1) Triangle"
    print "2) Rectangle"
    print "3) Trapazoid"
    print "4) Rhombus"
    print "5) Circle"
    e = int(raw_input("What do you want to do?: "))
    if e == 1: math.triangle(float(raw_input("Base: ")), float(raw_input("Hight: ")))
    elif e == 2: math.rectangle(float(raw_input("Lengh: ")), float(raw_input("Width: ")))
    elif e == 5: math.circle(float(raw_input("Radius: ")))
    else:
        print "Please choose a valid option"
        raw_input("Press enter to continue...")    
    menu()
def slope(): math.slope(float(raw_input("First y: ")),float(raw_input("Second y: ")),float(raw_input("First x: ")),float(raw_input("Second x: ")))
def sim():
    print "1) Add"
    print "2) Subtract"
    print "3) Multiply"    
    print "4) Divide"
    c = int(raw_input("what do you want to do?: "))
    if c == 1: math.add(float(raw_input("First Number: ")),float(raw_input("Second Number: ")))
    elif c == 2: math.sub(float(raw_input("First Number: ")),float(raw_input("Second Number: ")))
    elif c == 3: math.mul(float(raw_input("First Number: ")),float(raw_input("Second Number: ")))
    elif c == 4: math.div(float(raw_input("First Number: ")),float(raw_input("Second Number: ")))
    else:
        print "Please choose a valid option"
        raw_input("Press enter to continue...")    
    menu()
def adv():
    print "1) Slope Finder"
    print "2) Area Finder"
    d = int(raw_input("What do you want to do?: "))
    if d == 1: slope()
    elif d == 2: area()
    else:
        print "Please choose a valid option"
        raw_input("Press enter to continue...")
    menu()    
def menu():
    print "1) Simple Calculator"
    print "2) Advanced calculators"    
    a = int(raw_input("what do you want to do?: "))
    if a == 1: sim()
    elif a == 2: adv()
    else:
        print "Please choose a valid option"
        raw_input("Press enter to continue...")
        menu()
menu()
