Let's get this math done. We have 524 and we're going to multiply it by 10. This is the same as taking 524 and adding it to itself 10 times.
Step 1: 0 + 524 = 524
Step 2: 524 + 524 = 1048
Step 3: 1048 + 524 = 1572
Step 4: 1572 + 524 = 2096
Step 5: 2096 + 524 = 2620
Step 6: 2620 + 524 = 3144
Step 7: 3144 + 524 = 3668
Step 8: 3668 + 524 = 4192
Step 9: 4192 + 524 = 4716
Step 10: 4716 + 524 = 5240

So, 524*10 = 5240
