OK, let's work through this together. We're starting with 152 and we're going to multiply it by 13, which means we add 152 to itself 13 times.
Step 1: 0 + 152 = 152
Step 2: 152 + 152 = 304
Step 3: 304 + 152 = 456
Step 4: 456 + 152 = 608
Step 5: 608 + 152 = 760
Step 6: 760 + 152 = 912
Step 7: 912 + 152 = 1064
Step 8: 1064 + 152 = 1216
Step 9: 1216 + 152 = 1368
Step 10: 1368 + 152 = 1520
Step 11: 1520 + 152 = 1672
Step 12: 1672 + 152 = 1824
Step 13: 1824 + 152 = 1976

So, 152*13 = 1976
