OK, let's crack this. We're given 2 and our task is to multiply it by 18. Essentially, we'll be adding 2 to itself 18 times.
Step 1: 0 + 2 = 2
Step 2: 2 + 2 = 4
Step 3: 4 + 2 = 6
Step 4: 6 + 2 = 8
Step 5: 8 + 2 = 10
Step 6: 10 + 2 = 12
Step 7: 12 + 2 = 14
Step 8: 14 + 2 = 16
Step 9: 16 + 2 = 18
Step 10: 18 + 2 = 20
Step 11: 20 + 2 = 22
Step 12: 22 + 2 = 24
Step 13: 24 + 2 = 26
Step 14: 26 + 2 = 28
Step 15: 28 + 2 = 30
Step 16: 30 + 2 = 32
Step 17: 32 + 2 = 34
Step 18: 34 + 2 = 36

So, 2*18 = 36
