Sure thing, let's get straight to it. We start with 253 and we're going to multiply it by 19, which means adding 253 to itself 19 times.
Step 1: 0 + 253 = 253
Step 2: 253 + 253 = 506
Step 3: 506 + 253 = 759
Step 4: 759 + 253 = 1012
Step 5: 1012 + 253 = 1265
Step 6: 1265 + 253 = 1518
Step 7: 1518 + 253 = 1771
Step 8: 1771 + 253 = 2024
Step 9: 2024 + 253 = 2277
Step 10: 2277 + 253 = 2530
Step 11: 2530 + 253 = 2783
Step 12: 2783 + 253 = 3036
Step 13: 3036 + 253 = 3289
Step 14: 3289 + 253 = 3542
Step 15: 3542 + 253 = 3795
Step 16: 3795 + 253 = 4048
Step 17: 4048 + 253 = 4301
Step 18: 4301 + 253 = 4554
Step 19: 4554 + 253 = 4807

So, 253*19 = 4807
