In front of you are specially designed ties, without which any mathematician or computer scientist should not come up on the street. Thus designed ties encourage working enthusiasm, awaken creativity, but can be very useful in the work. On these ties can be found the formula which is hard to remember, keyboard, mouse or headphones. Very practical! We all know how mathematicians and computer scientist want to be different from others, and these ties can really serve them well. So, if you find yourself in a situation where you should go on at a friend’s birthday, which was very often in front of the computer, or, instead of crossword puzzles solve problems in mathematics, be sure to buy him this tie. It will certainly be thrilled, and you will not make a mistake in choosing a gift!
