Care about how you think at banks to. Have had some weird math shitYou have 100 light bulbs offyou flip every first switch then every 2nd switch every 3rd switch every 4th swtich.......100th switch.which light bulbs are still on. Do that without paper in a non mechanical way in a few minutes. You also have the ones where they dont care what the answer is just how you think.how many bricks are used each year in the uk to build new houses, how many piano tuners are in the uk?
