Alright, let's solve this math problem step by step. First, we have the number 260. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 12. So, we're going to take the number 260 and add it to itself 12 times.
Step 1: 0 + 260 = 260
Step 2: 260 + 260 = 520
Step 3: 520 + 260 = 780
Step 4: 780 + 260 = 1040
Step 5: 1040 + 260 = 1300
Step 6: 1300 + 260 = 1560
Step 7: 1560 + 260 = 1820
Step 8: 1820 + 260 = 2080
Step 9: 2080 + 260 = 2340
Step 10: 2340 + 260 = 2600
Step 11: 2600 + 260 = 2860
Step 12: 2860 + 260 = 3120

So, 260*12 = 3120
