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 17. So, we're going to take the number 260 and add it to itself 17 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
Step 13: 3120 + 260 = 3380
Step 14: 3380 + 260 = 3640
Step 15: 3640 + 260 = 3900
Step 16: 3900 + 260 = 4160
Step 17: 4160 + 260 = 4420

So, 260*17 = 4420
