OK, let's work through this together. We're starting with 239 and we're going to multiply it by 30, which means we add 239 to itself 30 times.
Step 1: 0 + 239 = 239
Step 2: 239 + 239 = 478
Step 3: 478 + 239 = 717
Step 4: 717 + 239 = 956
Step 5: 956 + 239 = 1195
Step 6: 1195 + 239 = 1434
Step 7: 1434 + 239 = 1673
Step 8: 1673 + 239 = 1912
Step 9: 1912 + 239 = 2151
Step 10: 2151 + 239 = 2390
Step 11: 2390 + 239 = 2629
Step 12: 2629 + 239 = 2868
Step 13: 2868 + 239 = 3107
Step 14: 3107 + 239 = 3346
Step 15: 3346 + 239 = 3585
Step 16: 3585 + 239 = 3824
Step 17: 3824 + 239 = 4063
Step 18: 4063 + 239 = 4302
Step 19: 4302 + 239 = 4541
Step 20: 4541 + 239 = 4780
Step 21: 4780 + 239 = 5019
Step 22: 5019 + 239 = 5258
Step 23: 5258 + 239 = 5497
Step 24: 5497 + 239 = 5736
Step 25: 5736 + 239 = 5975
Step 26: 5975 + 239 = 6214
Step 27: 6214 + 239 = 6453
Step 28: 6453 + 239 = 6692
Step 29: 6692 + 239 = 6931
Step 30: 6931 + 239 = 7170

So, 239*30 = 7170
