Alright, let's solve this math problem step by step. First, we have the number 253. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 23. So, we're going to take the number 253 and add it to itself 23 times.
Step 1: 0 + 253 = 253
Step 2: 253 + 253 = 506
Step 3: 506 + 253 = 759
Step 4: 759 + 253 = 1012
Step 5: 1012 + 253 = 1265
Step 6: 1265 + 253 = 1518
Step 7: 1518 + 253 = 1771
Step 8: 1771 + 253 = 2024
Step 9: 2024 + 253 = 2277
Step 10: 2277 + 253 = 2530
Step 11: 2530 + 253 = 2783
Step 12: 2783 + 253 = 3036
Step 13: 3036 + 253 = 3289
Step 14: 3289 + 253 = 3542
Step 15: 3542 + 253 = 3795
Step 16: 3795 + 253 = 4048
Step 17: 4048 + 253 = 4301
Step 18: 4301 + 253 = 4554
Step 19: 4554 + 253 = 4807
Step 20: 4807 + 253 = 5060
Step 21: 5060 + 253 = 5313
Step 22: 5313 + 253 = 5566
Step 23: 5566 + 253 = 5819

So, 253*23 = 5819
