OK, let's crack this. We're given 148 and our task is to multiply it by 38. Essentially, we'll be adding 148 to itself 38 times.
Step 1: 0 + 148 = 148
Step 2: 148 + 148 = 296
Step 3: 296 + 148 = 444
Step 4: 444 + 148 = 592
Step 5: 592 + 148 = 740
Step 6: 740 + 148 = 888
Step 7: 888 + 148 = 1036
Step 8: 1036 + 148 = 1184
Step 9: 1184 + 148 = 1332
Step 10: 1332 + 148 = 1480
Step 11: 1480 + 148 = 1628
Step 12: 1628 + 148 = 1776
Step 13: 1776 + 148 = 1924
Step 14: 1924 + 148 = 2072
Step 15: 2072 + 148 = 2220
Step 16: 2220 + 148 = 2368
Step 17: 2368 + 148 = 2516
Step 18: 2516 + 148 = 2664
Step 19: 2664 + 148 = 2812
Step 20: 2812 + 148 = 2960
Step 21: 2960 + 148 = 3108
Step 22: 3108 + 148 = 3256
Step 23: 3256 + 148 = 3404
Step 24: 3404 + 148 = 3552
Step 25: 3552 + 148 = 3700
Step 26: 3700 + 148 = 3848
Step 27: 3848 + 148 = 3996
Step 28: 3996 + 148 = 4144
Step 29: 4144 + 148 = 4292
Step 30: 4292 + 148 = 4440
Step 31: 4440 + 148 = 4588
Step 32: 4588 + 148 = 4736
Step 33: 4736 + 148 = 4884
Step 34: 4884 + 148 = 5032
Step 35: 5032 + 148 = 5180
Step 36: 5180 + 148 = 5328
Step 37: 5328 + 148 = 5476
Step 38: 5476 + 148 = 5624

So, 148*38 = 5624
