OK, let's work through this together. We're starting with 237 and we're going to multiply it by 24, which means we add 237 to itself 24 times.
Step 1: 0 + 237 = 237
Step 2: 237 + 237 = 474
Step 3: 474 + 237 = 711
Step 4: 711 + 237 = 948
Step 5: 948 + 237 = 1185
Step 6: 1185 + 237 = 1422
Step 7: 1422 + 237 = 1659
Step 8: 1659 + 237 = 1896
Step 9: 1896 + 237 = 2133
Step 10: 2133 + 237 = 2370
Step 11: 2370 + 237 = 2607
Step 12: 2607 + 237 = 2844
Step 13: 2844 + 237 = 3081
Step 14: 3081 + 237 = 3318
Step 15: 3318 + 237 = 3555
Step 16: 3555 + 237 = 3792
Step 17: 3792 + 237 = 4029
Step 18: 4029 + 237 = 4266
Step 19: 4266 + 237 = 4503
Step 20: 4503 + 237 = 4740
Step 21: 4740 + 237 = 4977
Step 22: 4977 + 237 = 5214
Step 23: 5214 + 237 = 5451
Step 24: 5451 + 237 = 5688

So, 237*24 = 5688
