Alright, let's solve this math problem step by step. First, we have the number 894. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 24. So, we're going to take the number 894 and add it to itself 24 times.
Step 1: 0 + 894 = 894
Step 2: 894 + 894 = 1788
Step 3: 1788 + 894 = 2682
Step 4: 2682 + 894 = 3576
Step 5: 3576 + 894 = 4470
Step 6: 4470 + 894 = 5364
Step 7: 5364 + 894 = 6258
Step 8: 6258 + 894 = 7152
Step 9: 7152 + 894 = 8046
Step 10: 8046 + 894 = 8940
Step 11: 8940 + 894 = 9834
Step 12: 9834 + 894 = 10728
Step 13: 10728 + 894 = 11622
Step 14: 11622 + 894 = 12516
Step 15: 12516 + 894 = 13410
Step 16: 13410 + 894 = 14304
Step 17: 14304 + 894 = 15198
Step 18: 15198 + 894 = 16092
Step 19: 16092 + 894 = 16986
Step 20: 16986 + 894 = 17880
Step 21: 17880 + 894 = 18774
Step 22: 18774 + 894 = 19668
Step 23: 19668 + 894 = 20562
Step 24: 20562 + 894 = 21456

So, 894*24 = 21456
