Alright, let's solve this math problem step by step. First, we have the number 187. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 7. So, we're going to take the number 187 and add it to itself 7 times.
Step 1: 0 + 187 = 187
Step 2: 187 + 187 = 374
Step 3: 374 + 187 = 561
Step 4: 561 + 187 = 748
Step 5: 748 + 187 = 935
Step 6: 935 + 187 = 1122
Step 7: 1122 + 187 = 1309

So, 187*7 = 1309
