Alright, let's solve this math problem step by step. First, we have the number 7. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 28. So, we're going to take the number 7 and add it to itself 28 times.
Step 1: 0 + 7 = 7
Step 2: 7 + 7 = 14
Step 3: 14 + 7 = 21
Step 4: 21 + 7 = 28
Step 5: 28 + 7 = 35
Step 6: 35 + 7 = 42
Step 7: 42 + 7 = 49
Step 8: 49 + 7 = 56
Step 9: 56 + 7 = 63
Step 10: 63 + 7 = 70
Step 11: 70 + 7 = 77
Step 12: 77 + 7 = 84
Step 13: 84 + 7 = 91
Step 14: 91 + 7 = 98
Step 15: 98 + 7 = 105
Step 16: 105 + 7 = 112
Step 17: 112 + 7 = 119
Step 18: 119 + 7 = 126
Step 19: 126 + 7 = 133
Step 20: 133 + 7 = 140
Step 21: 140 + 7 = 147
Step 22: 147 + 7 = 154
Step 23: 154 + 7 = 161
Step 24: 161 + 7 = 168
Step 25: 168 + 7 = 175
Step 26: 175 + 7 = 182
Step 27: 182 + 7 = 189
Step 28: 189 + 7 = 196

So, 7*28 = 196
