Alright, let's solve this math problem step by step. First, we have the number 212. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 15. So, we're going to take the number 212 and add it to itself 15 times.
Step 1: 0 + 212 = 212
Step 2: 212 + 212 = 424
Step 3: 424 + 212 = 636
Step 4: 636 + 212 = 848
Step 5: 848 + 212 = 1060
Step 6: 1060 + 212 = 1272
Step 7: 1272 + 212 = 1484
Step 8: 1484 + 212 = 1696
Step 9: 1696 + 212 = 1908
Step 10: 1908 + 212 = 2120
Step 11: 2120 + 212 = 2332
Step 12: 2332 + 212 = 2544
Step 13: 2544 + 212 = 2756
Step 14: 2756 + 212 = 2968
Step 15: 2968 + 212 = 3180

So, 212*15 = 3180
