Sure thing, let's get straight to it. We start with 149 and we're going to multiply it by 7, which means adding 149 to itself 7 times.
Step 1: 0 + 149 = 149
Step 2: 149 + 149 = 298
Step 3: 298 + 149 = 447
Step 4: 447 + 149 = 596
Step 5: 596 + 149 = 745
Step 6: 745 + 149 = 894
Step 7: 894 + 149 = 1043

So, 149*7 = 1043
