Alright, let's solve this math problem step by step. First, we have the number 266. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 43. So, we're going to take the number 266 and add it to itself 43 times.
Step 1: 0 + 266 = 266
Step 2: 266 + 266 = 532
Step 3: 532 + 266 = 798
Step 4: 798 + 266 = 1064
Step 5: 1064 + 266 = 1330
Step 6: 1330 + 266 = 1596
Step 7: 1596 + 266 = 1862
Step 8: 1862 + 266 = 2128
Step 9: 2128 + 266 = 2394
Step 10: 2394 + 266 = 2660
Step 11: 2660 + 266 = 2926
Step 12: 2926 + 266 = 3192
Step 13: 3192 + 266 = 3458
Step 14: 3458 + 266 = 3724
Step 15: 3724 + 266 = 3990
Step 16: 3990 + 266 = 4256
Step 17: 4256 + 266 = 4522
Step 18: 4522 + 266 = 4788
Step 19: 4788 + 266 = 5054
Step 20: 5054 + 266 = 5320
Step 21: 5320 + 266 = 5586
Step 22: 5586 + 266 = 5852
Step 23: 5852 + 266 = 6118
Step 24: 6118 + 266 = 6384
Step 25: 6384 + 266 = 6650
Step 26: 6650 + 266 = 6916
Step 27: 6916 + 266 = 7182
Step 28: 7182 + 266 = 7448
Step 29: 7448 + 266 = 7714
Step 30: 7714 + 266 = 7980
Step 31: 7980 + 266 = 8246
Step 32: 8246 + 266 = 8512
Step 33: 8512 + 266 = 8778
Step 34: 8778 + 266 = 9044
Step 35: 9044 + 266 = 9310
Step 36: 9310 + 266 = 9576
Step 37: 9576 + 266 = 9842
Step 38: 9842 + 266 = 10108
Step 39: 10108 + 266 = 10374
Step 40: 10374 + 266 = 10640
Step 41: 10640 + 266 = 10906
Step 42: 10906 + 266 = 11172
Step 43: 11172 + 266 = 11438

So, 266*43 = 11438
