OK, let's work through this together. We're starting with 358 and we're going to multiply it by 6, which means we add 358 to itself 6 times.
Step 1: 0 + 358 = 358
Step 2: 358 + 358 = 716
Step 3: 716 + 358 = 1074
Step 4: 1074 + 358 = 1432
Step 5: 1432 + 358 = 1790
Step 6: 1790 + 358 = 2148

So, 358*6 = 2148
