Lizzy: Darry is a roofer and has to climb ladders multiple times a day. He climbs his full ladder, which has 11 steps, 10 times today. He also climbs his smaller ladder, which has 6 steps, 7 times today. He did not climb any steps otherwise. In total, how many times has Darry climbed a step today?.
Me: Hmmm, let me think. I think this is the detailed solution:
Climbing the full ladder means Darry has climbed 11 steps * 10 times = 110 steps so far. On his smaller ladder, he has climbed 6 steps * 7 times = 42 steps. So he has climbed a step a total of 110 + 42 = 152 times today. Final answer: 152.
