Sure thing! We've got 898 and we're gonna multiply it by 24. That's the same as adding 898 to itself 24 times.
Step 1: 0 + 898 = 898
Step 2: 898 + 898 = 1796
Step 3: 1796 + 898 = 2694
Step 4: 2694 + 898 = 3592
Step 5: 3592 + 898 = 4490
Step 6: 4490 + 898 = 5388
Step 7: 5388 + 898 = 6286
Step 8: 6286 + 898 = 7184
Step 9: 7184 + 898 = 8082
Step 10: 8082 + 898 = 8980
Step 11: 8980 + 898 = 9878
Step 12: 9878 + 898 = 10776
Step 13: 10776 + 898 = 11674
Step 14: 11674 + 898 = 12572
Step 15: 12572 + 898 = 13470
Step 16: 13470 + 898 = 14368
Step 17: 14368 + 898 = 15266
Step 18: 15266 + 898 = 16164
Step 19: 16164 + 898 = 17062
Step 20: 17062 + 898 = 17960
Step 21: 17960 + 898 = 18858
Step 22: 18858 + 898 = 19756
Step 23: 19756 + 898 = 20654
Step 24: 20654 + 898 = 21552

So, 898*24 = 21552
