Let's roll up our sleeves and solve this. We have 190 and we're going to multiply it by 10, essentially adding 190 to itself 10 times.
Step 1: 0 + 190 = 190
Step 2: 190 + 190 = 380
Step 3: 380 + 190 = 570
Step 4: 570 + 190 = 760
Step 5: 760 + 190 = 950
Step 6: 950 + 190 = 1140
Step 7: 1140 + 190 = 1330
Step 8: 1330 + 190 = 1520
Step 9: 1520 + 190 = 1710
Step 10: 1710 + 190 = 1900

So, 190*10 = 1900
