Alright, let's solve this math problem step by step. First, we have the number 153. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 14. So, we're going to take the number 153 and add it to itself 14 times.
Step 1: 0 + 153 = 153
Step 2: 153 + 153 = 306
Step 3: 306 + 153 = 459
Step 4: 459 + 153 = 612
Step 5: 612 + 153 = 765
Step 6: 765 + 153 = 918
Step 7: 918 + 153 = 1071
Step 8: 1071 + 153 = 1224
Step 9: 1224 + 153 = 1377
Step 10: 1377 + 153 = 1530
Step 11: 1530 + 153 = 1683
Step 12: 1683 + 153 = 1836
Step 13: 1836 + 153 = 1989
Step 14: 1989 + 153 = 2142

So, 153*14 = 2142
