Sure thing! We've got 215 and we're gonna multiply it by 19. That's the same as adding 215 to itself 19 times.
Step 1: 0 + 215 = 215
Step 2: 215 + 215 = 430
Step 3: 430 + 215 = 645
Step 4: 645 + 215 = 860
Step 5: 860 + 215 = 1075
Step 6: 1075 + 215 = 1290
Step 7: 1290 + 215 = 1505
Step 8: 1505 + 215 = 1720
Step 9: 1720 + 215 = 1935
Step 10: 1935 + 215 = 2150
Step 11: 2150 + 215 = 2365
Step 12: 2365 + 215 = 2580
Step 13: 2580 + 215 = 2795
Step 14: 2795 + 215 = 3010
Step 15: 3010 + 215 = 3225
Step 16: 3225 + 215 = 3440
Step 17: 3440 + 215 = 3655
Step 18: 3655 + 215 = 3870
Step 19: 3870 + 215 = 4085

So, 215*19 = 4085
