OK, let's work through this together. We're starting with 290 and we're going to multiply it by 7, which means we add 290 to itself 7 times.
Step 1: 0 + 290 = 290
Step 2: 290 + 290 = 580
Step 3: 580 + 290 = 870
Step 4: 870 + 290 = 1160
Step 5: 1160 + 290 = 1450
Step 6: 1450 + 290 = 1740
Step 7: 1740 + 290 = 2030

So, 290*7 = 2030
