Sure thing, let's get straight to it. We start with 10 and we're going to multiply it by 19, which means adding 10 to itself 19 times.
Step 1: 0 + 10 = 10
Step 2: 10 + 10 = 20
Step 3: 20 + 10 = 30
Step 4: 30 + 10 = 40
Step 5: 40 + 10 = 50
Step 6: 50 + 10 = 60
Step 7: 60 + 10 = 70
Step 8: 70 + 10 = 80
Step 9: 80 + 10 = 90
Step 10: 90 + 10 = 100
Step 11: 100 + 10 = 110
Step 12: 110 + 10 = 120
Step 13: 120 + 10 = 130
Step 14: 130 + 10 = 140
Step 15: 140 + 10 = 150
Step 16: 150 + 10 = 160
Step 17: 160 + 10 = 170
Step 18: 170 + 10 = 180
Step 19: 180 + 10 = 190

So, 10*19 = 190
