Let's get this math done. We have 222 and we're going to multiply it by 25. This is the same as taking 222 and adding it to itself 25 times.
Step 1: 0 + 222 = 222
Step 2: 222 + 222 = 444
Step 3: 444 + 222 = 666
Step 4: 666 + 222 = 888
Step 5: 888 + 222 = 1110
Step 6: 1110 + 222 = 1332
Step 7: 1332 + 222 = 1554
Step 8: 1554 + 222 = 1776
Step 9: 1776 + 222 = 1998
Step 10: 1998 + 222 = 2220
Step 11: 2220 + 222 = 2442
Step 12: 2442 + 222 = 2664
Step 13: 2664 + 222 = 2886
Step 14: 2886 + 222 = 3108
Step 15: 3108 + 222 = 3330
Step 16: 3330 + 222 = 3552
Step 17: 3552 + 222 = 3774
Step 18: 3774 + 222 = 3996
Step 19: 3996 + 222 = 4218
Step 20: 4218 + 222 = 4440
Step 21: 4440 + 222 = 4662
Step 22: 4662 + 222 = 4884
Step 23: 4884 + 222 = 5106
Step 24: 5106 + 222 = 5328
Step 25: 5328 + 222 = 5550

So, 222*25 = 5550
