Alright, let's solve this math problem step by step. First, we have the number 245. 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 245 and add it to itself 12 times.
Step 1: 0 + 245 = 245
Step 2: 245 + 245 = 490
Step 3: 490 + 245 = 735
Step 4: 735 + 245 = 980
Step 5: 980 + 245 = 1225
Step 6: 1225 + 245 = 1470
Step 7: 1470 + 245 = 1715
Step 8: 1715 + 245 = 1960
Step 9: 1960 + 245 = 2205
Step 10: 2205 + 245 = 2450
Step 11: 2450 + 245 = 2695
Step 12: 2695 + 245 = 2940

So, 245*12 = 2940
