Sure thing, let's get straight to it. We start with 350 and we're going to multiply it by 6, which means adding 350 to itself 6 times.
Step 1: 0 + 350 = 350
Step 2: 350 + 350 = 700
Step 3: 700 + 350 = 1050
Step 4: 1050 + 350 = 1400
Step 5: 1400 + 350 = 1750
Step 6: 1750 + 350 = 2100

So, 350*6 = 2100
