Sure thing! We've got 79 and we're gonna multiply it by 18. That's the same as adding 79 to itself 18 times.
Step 1: 0 + 79 = 79
Step 2: 79 + 79 = 158
Step 3: 158 + 79 = 237
Step 4: 237 + 79 = 316
Step 5: 316 + 79 = 395
Step 6: 395 + 79 = 474
Step 7: 474 + 79 = 553
Step 8: 553 + 79 = 632
Step 9: 632 + 79 = 711
Step 10: 711 + 79 = 790
Step 11: 790 + 79 = 869
Step 12: 869 + 79 = 948
Step 13: 948 + 79 = 1027
Step 14: 1027 + 79 = 1106
Step 15: 1106 + 79 = 1185
Step 16: 1185 + 79 = 1264
Step 17: 1264 + 79 = 1343
Step 18: 1343 + 79 = 1422

So, 79*18 = 1422
