Sure thing! We've got 157 and we're gonna multiply it by 10. That's the same as adding 157 to itself 10 times.
Step 1: 0 + 157 = 157
Step 2: 157 + 157 = 314
Step 3: 314 + 157 = 471
Step 4: 471 + 157 = 628
Step 5: 628 + 157 = 785
Step 6: 785 + 157 = 942
Step 7: 942 + 157 = 1099
Step 8: 1099 + 157 = 1256
Step 9: 1256 + 157 = 1413
Step 10: 1413 + 157 = 1570

So, 157*10 = 1570
