Sure thing! We've got 5 and we're gonna multiply it by 30. That's the same as adding 5 to itself 30 times.
Step 1: 0 + 5 = 5
Step 2: 5 + 5 = 10
Step 3: 10 + 5 = 15
Step 4: 15 + 5 = 20
Step 5: 20 + 5 = 25
Step 6: 25 + 5 = 30
Step 7: 30 + 5 = 35
Step 8: 35 + 5 = 40
Step 9: 40 + 5 = 45
Step 10: 45 + 5 = 50
Step 11: 50 + 5 = 55
Step 12: 55 + 5 = 60
Step 13: 60 + 5 = 65
Step 14: 65 + 5 = 70
Step 15: 70 + 5 = 75
Step 16: 75 + 5 = 80
Step 17: 80 + 5 = 85
Step 18: 85 + 5 = 90
Step 19: 90 + 5 = 95
Step 20: 95 + 5 = 100
Step 21: 100 + 5 = 105
Step 22: 105 + 5 = 110
Step 23: 110 + 5 = 115
Step 24: 115 + 5 = 120
Step 25: 120 + 5 = 125
Step 26: 125 + 5 = 130
Step 27: 130 + 5 = 135
Step 28: 135 + 5 = 140
Step 29: 140 + 5 = 145
Step 30: 145 + 5 = 150

So, 5*30 = 150
