Let's get this math done. We have 748 and we're going to multiply it by 10. This is the same as taking 748 and adding it to itself 10 times.
Step 1: 0 + 748 = 748
Step 2: 748 + 748 = 1496
Step 3: 1496 + 748 = 2244
Step 4: 2244 + 748 = 2992
Step 5: 2992 + 748 = 3740
Step 6: 3740 + 748 = 4488
Step 7: 4488 + 748 = 5236
Step 8: 5236 + 748 = 5984
Step 9: 5984 + 748 = 6732
Step 10: 6732 + 748 = 7480

So, 748*10 = 7480
