VB.NET คำนวณใน โจทย์ เดียว 3คำตอบ รบกวนช่วยชี้แนะทีครับผม

ans = (100+23)x12
ans1 = 100+ans
ans2 = (ans1x100)-10



i= 100,23,12,100,ans,ans1,100,10
o= +,x,+,x,-
p= ans,ans1,ans2

num1 = 100
num2 = 23
num3 = 12
num4 = 100
num5 = ans
num6 = ans1
num7 = 100
num8 = 10

(num1+num2)xnum3
ans = (num1+num2)xnum3
Printf = (ans)
ans1 = num5+num6
Printf = (ans1)
(num6xnum7)-num8
ans2 = (num6xnum7)-num8
Printf = (ans2)


Dim num1 as Integer
Dim num2 as Integer
Dim num3 as Integer
Dim num4 as Integer
Dim num5 as Integer
Dim num6 as Integer 
Dim num7 as Integer
Dim num8 as Integer  
Dim ans as Integer
Dim ans1 as Integer
Dim ans2 as Integer


num1 = 100
num2 = 23
num3 = 12
num4 = 100
num5 = ans
num6 = ans1
num7 = 100
num8 = 10

ans = (num1+num2)xnum3
ans1 = num5+num6
ans2 = (num6xnum7)-num8
หรืออันนี้ หว่า
	ans=(100+23)x12	
	ans1=100+ans
	ans2=(ansx100)-10
	input   = 100,23,12,10,ans,ans1	
	process = +,-,x
	Output  = ans2 
		num1 = 100
		num2 = 23		
		num3 = 12	
		num4 = 10
		num5 = ans
		num6 = ans1
	num5=(num1+num2)xnum3
	num6=num1+num5
	ans2=(num6xnum1)-num4
	printf(ans2)


	Dim num1 as Integer
	Dim num2 as Integer
	Dim num3 as Integer
	Dim num4 as Integer
	Dim num5 as Integer
	Dim num6 as Integer
	Dim ans2 as Integer
		num1 = 100
		num2 = 23
		num3 = 12
		num4 = 10
		num5 = ans
		num6 = ans1
	num5=(num1+num2)xnum3
	num6=num1+num5
	ans2=(num6xnum1)-num4
printf(ans2)
