Alright, let's solve this math problem step by step. First, we have the number 750. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 25. So, we're going to take the number 750 and add it to itself 25 times.
Step 1: 0 + 750 = 750
Step 2: 750 + 750 = 1500
Step 3: 1500 + 750 = 2250
Step 4: 2250 + 750 = 3000
Step 5: 3000 + 750 = 3750
Step 6: 3750 + 750 = 4500
Step 7: 4500 + 750 = 5250
Step 8: 5250 + 750 = 6000
Step 9: 6000 + 750 = 6750
Step 10: 6750 + 750 = 7500
Step 11: 7500 + 750 = 8250
Step 12: 8250 + 750 = 9000
Step 13: 9000 + 750 = 9750
Step 14: 9750 + 750 = 10500
Step 15: 10500 + 750 = 11250
Step 16: 11250 + 750 = 12000
Step 17: 12000 + 750 = 12750
Step 18: 12750 + 750 = 13500
Step 19: 13500 + 750 = 14250
Step 20: 14250 + 750 = 15000
Step 21: 15000 + 750 = 15750
Step 22: 15750 + 750 = 16500
Step 23: 16500 + 750 = 17250
Step 24: 17250 + 750 = 18000
Step 25: 18000 + 750 = 18750

So, 750*25 = 18750
