Alright, let's solve this math problem step by step. First, we have the number 24. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 13. So, we're going to take the number 24 and add it to itself 13 times.
Step 1: 0 + 24 = 24
Step 2: 24 + 24 = 48
Step 3: 48 + 24 = 72
Step 4: 72 + 24 = 96
Step 5: 96 + 24 = 120
Step 6: 120 + 24 = 144
Step 7: 144 + 24 = 168
Step 8: 168 + 24 = 192
Step 9: 192 + 24 = 216
Step 10: 216 + 24 = 240
Step 11: 240 + 24 = 264
Step 12: 264 + 24 = 288
Step 13: 288 + 24 = 312

So, 24*13 = 312
