Alright, let's solve this math problem step by step. First, we have the number 10. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 26. So, we're going to take the number 10 and add it to itself 26 times.
Step 1: 0 + 10 = 10
Step 2: 10 + 10 = 20
Step 3: 20 + 10 = 30
Step 4: 30 + 10 = 40
Step 5: 40 + 10 = 50
Step 6: 50 + 10 = 60
Step 7: 60 + 10 = 70
Step 8: 70 + 10 = 80
Step 9: 80 + 10 = 90
Step 10: 90 + 10 = 100
Step 11: 100 + 10 = 110
Step 12: 110 + 10 = 120
Step 13: 120 + 10 = 130
Step 14: 130 + 10 = 140
Step 15: 140 + 10 = 150
Step 16: 150 + 10 = 160
Step 17: 160 + 10 = 170
Step 18: 170 + 10 = 180
Step 19: 180 + 10 = 190
Step 20: 190 + 10 = 200
Step 21: 200 + 10 = 210
Step 22: 210 + 10 = 220
Step 23: 220 + 10 = 230
Step 24: 230 + 10 = 240
Step 25: 240 + 10 = 250
Step 26: 250 + 10 = 260

So, 10*26 = 260
