Without delay, let's solve this. We've got 1 and we will be multiplying it by 30, that is, adding 1 to itself 30 times.
Step 1: 0 + 1 = 1
Step 2: 1 + 1 = 2
Step 3: 2 + 1 = 3
Step 4: 3 + 1 = 4
Step 5: 4 + 1 = 5
Step 6: 5 + 1 = 6
Step 7: 6 + 1 = 7
Step 8: 7 + 1 = 8
Step 9: 8 + 1 = 9
Step 10: 9 + 1 = 10
Step 11: 10 + 1 = 11
Step 12: 11 + 1 = 12
Step 13: 12 + 1 = 13
Step 14: 13 + 1 = 14
Step 15: 14 + 1 = 15
Step 16: 15 + 1 = 16
Step 17: 16 + 1 = 17
Step 18: 17 + 1 = 18
Step 19: 18 + 1 = 19
Step 20: 19 + 1 = 20
Step 21: 20 + 1 = 21
Step 22: 21 + 1 = 22
Step 23: 22 + 1 = 23
Step 24: 23 + 1 = 24
Step 25: 24 + 1 = 25
Step 26: 25 + 1 = 26
Step 27: 26 + 1 = 27
Step 28: 27 + 1 = 28
Step 29: 28 + 1 = 29
Step 30: 29 + 1 = 30

So, 1*30 = 30
