OK, let's crack this. We're given 113 and our task is to multiply it by 7. Essentially, we'll be adding 113 to itself 7 times.
Step 1: 0 + 113 = 113
Step 2: 113 + 113 = 226
Step 3: 226 + 113 = 339
Step 4: 339 + 113 = 452
Step 5: 452 + 113 = 565
Step 6: 565 + 113 = 678
Step 7: 678 + 113 = 791

So, 113*7 = 791
