Alright, let's solve this math problem step by step. First, we have the number 215. 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 215 and add it to itself 7 times.
Step 1: 0 + 215 = 215
Step 2: 215 + 215 = 430
Step 3: 430 + 215 = 645
Step 4: 645 + 215 = 860
Step 5: 860 + 215 = 1075
Step 6: 1075 + 215 = 1290
Step 7: 1290 + 215 = 1505

So, 215*7 = 1505
