Alright, let's solve this math problem step by step. First, we have the number 735. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 10. So, we're going to take the number 735 and add it to itself 10 times.
Step 1: 0 + 735 = 735
Step 2: 735 + 735 = 1470
Step 3: 1470 + 735 = 2205
Step 4: 2205 + 735 = 2940
Step 5: 2940 + 735 = 3675
Step 6: 3675 + 735 = 4410
Step 7: 4410 + 735 = 5145
Step 8: 5145 + 735 = 5880
Step 9: 5880 + 735 = 6615
Step 10: 6615 + 735 = 7350

So, 735*10 = 7350
