Alright, let's solve this math problem step by step. First, we have the number 313. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 30. So, we're going to take the number 313 and add it to itself 30 times.
Step 1: 0 + 313 = 313
Step 2: 313 + 313 = 626
Step 3: 626 + 313 = 939
Step 4: 939 + 313 = 1252
Step 5: 1252 + 313 = 1565
Step 6: 1565 + 313 = 1878
Step 7: 1878 + 313 = 2191
Step 8: 2191 + 313 = 2504
Step 9: 2504 + 313 = 2817
Step 10: 2817 + 313 = 3130
Step 11: 3130 + 313 = 3443
Step 12: 3443 + 313 = 3756
Step 13: 3756 + 313 = 4069
Step 14: 4069 + 313 = 4382
Step 15: 4382 + 313 = 4695
Step 16: 4695 + 313 = 5008
Step 17: 5008 + 313 = 5321
Step 18: 5321 + 313 = 5634
Step 19: 5634 + 313 = 5947
Step 20: 5947 + 313 = 6260
Step 21: 6260 + 313 = 6573
Step 22: 6573 + 313 = 6886
Step 23: 6886 + 313 = 7199
Step 24: 7199 + 313 = 7512
Step 25: 7512 + 313 = 7825
Step 26: 7825 + 313 = 8138
Step 27: 8138 + 313 = 8451
Step 28: 8451 + 313 = 8764
Step 29: 8764 + 313 = 9077
Step 30: 9077 + 313 = 9390

So, 313*30 = 9390
