Sure thing! We've got 30 and we're gonna multiply it by 19. That's the same as adding 30 to itself 19 times.
Step 1: 0 + 30 = 30
Step 2: 30 + 30 = 60
Step 3: 60 + 30 = 90
Step 4: 90 + 30 = 120
Step 5: 120 + 30 = 150
Step 6: 150 + 30 = 180
Step 7: 180 + 30 = 210
Step 8: 210 + 30 = 240
Step 9: 240 + 30 = 270
Step 10: 270 + 30 = 300
Step 11: 300 + 30 = 330
Step 12: 330 + 30 = 360
Step 13: 360 + 30 = 390
Step 14: 390 + 30 = 420
Step 15: 420 + 30 = 450
Step 16: 450 + 30 = 480
Step 17: 480 + 30 = 510
Step 18: 510 + 30 = 540
Step 19: 540 + 30 = 570

So, 30*19 = 570
